Solution

The correct option is B
Snails

Different species use very different strategies for this. Some rely entirely on environmental cues. Thus, in some animals, the temperature at which fertilized eggs are kept determines whether the animals developing in the eggs will be male or female. In other animals, such as snails, individuals can change sex, indicating that sex is not genetically determined.
