The next three questions are based on the following passage

As little as three years before her birth, few would have thought that the child born Princess Alexandrina Victoria would eventually become Brittain's longest monarch, Queen Victoria. She was born in 1819, the only child of Edward, Duke of Kent, who was the fourth son of King George III. Ahead of Edward were three brothers, two of whom became king but none of whom produced a legitimate, , surviving heir, King George's eldest son, who was eventually crowned King George IV, secretly married a Catholic commoner, Maria Fitzherbert, in 1783. The marriage was never officially recognized, and in 1795, George was persuaded to marry a distant cousin, Caroline of Brunswick. The marriage was bitter, and the two had only one daughter, Princess Charlotte Augusta. She was popular in England where her eventual reign was welcome, but in a tragic event that shocked the nation, the princess and her stillborn son dies in childbirth in 1817.
Realizing the precarious position of the British throne, the remaining sons of King George III were motivated to marry and produce an heir. The first in line was Prince Frederick, the Duke of York. Frederick married Princess Frederica Charlotte of Prussia, but the two had no children. After Prince Frederick was Prince William, the Duke of Clarence. William married Princess Adelaide of Saxe-Meiningen, and they had two sickly daughters neither of whom survived infancy. Finally, Prince Edward, the Duke of Kent, threw his hat into the ring with his marriage to Princess Victoria of Saxe-Coburg-Saalfield. The Duke of Kent died less than a year after his daughter's birth, but the surviving Duchess of Kent was not unaware of the future possibilities for her daughter. She took every precaution to ensure that the young Princess Victoria was healthy and safe throughout her childhood.
Princess Victoria's uncle, William, succeeded his brother George IV to become King William IV. The new king recognized his niece as his future heir, but he did not necessarily trust her mother. As a result, he was determined to survive until Victoria's eighteenth birthday to ensure that she could rule in own right without the regency of the Duchess of Kent. The king's fervent prayers were answered: he died June, 1837, less than one month after Victoria turned eighteen. Through young and inexperienced, the young queen recognized the importance of her position and determined to rule fairly and wisely. The improbable princess who became queen ruled for more than sixty-three years, and her reign is considered to be one of the most important in British history.

Which of the following is a logical conclusion that can be drawn from the information in the passage above?

a. Victoria's long reign provided the opportunity for her to bring balance to England and right the wrongs that had occurred during the reigns of her uncles.
b. It was the death of Princess Charlotte Augusta that motivated the remaining princes to marry and start families.
c. The Duke of kent had hoped for a son but was delighted with his good fortune in producing the surviving heir that his brothers had failed to produce.
d. King William IV was unreasonably suspicious of the Duchess of Kent's motivations, as she cared only for her daughter's well-being.
