The correct answer is option D. It will remain the same.
Soft tissues are the tissues that connect and surrounds an organ. They are called soft tissues because they are very soft in nature.
These are not hardened by the process of ossification or calcification such as bone or teeth.
The most common soft tissues are muscles, ligaments, tendons or fascia.
Since they are very soft so they can cause severe damages or injuries.
To know about these, there are many types of waves used these days.
Such waves are then used to detect any problem by making it propagate through the tissues.
These waves have their own frequency and wavelength.
The propagation speed is the speed of wave at which any wave can move freely in a space.
The propagation speed is influenced by many factors. But frequency is not one of them.
Even if the frequency is changed, it won't affect the propagation speed as the propagation speed can only be affected by the stiffness and density of a medium.
Hence, option D is the correct option.
In soft tissues, if the frequency of a wave is increased, the propagation speed will remain the same.
