Question content area bottom Part 1 Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Use a comma to separate answers as​ needed.) A. The possible​ degree(s) is/are enter your response here because it must be less than the degree of either P or Q. B. The possible​ degree(s) is/are enter your response here because it must be equal to the lesser of the degrees of P and Q. C. The possible​ degree(s) is/are enter your response here because it cannot be higher than the degree of either P or Q but it can be less depending on which terms cancel. D. The possible​ degree(s) is/are enter your response here because it must be equal to the greater of the degrees of P and Q.
