Answer:
A) cells of the tail dying and the nutrients being absorbed and reused by the body
Explanation:
The tails of the tadpole die when metamorphosing into an adult frog through a process Called Apoptosis. Apoptosis happens when it’s necessary for the body to kill some cells for development or other factors.
The cells which are killed produces nutrients which are then used and reabsorbed back into the body system of the frog.
