b.... tortoise

Answer 2

Ans.

TSD or temperature dependent sex determination is defined as a method of sex determination that includes effect of temperature on larval or embryonic development and on sex determination of offspring. TSD is shown by many reptiles, such as crocodiles and lizards.

In lizards, eggs at high temperature develop into male progeny, while eggs at low temperature develop into female progeny.

In turtles, eggs at high temperature develop into female progeny, while eggs at low temperature develop into male progeny.
