The Researcher Determines That an Average Nest Incubation Temperature of 32

Multiple Choice

The researcher determines that an average nest incubation temperature of 32 - 33 ^$\circ$ C results in the birth of male crocodiles while higher and lower incubation temperatures result in female crocodiles.What is the most likely explanation for this phenomenon?

A) Incubation temperature results in a change in the crocodilian genome
B) Incubation temperature results in a change in the crocodilian proteome
C) Since this phenomenon is influenced by an external stimuli (temperature) ,it cannot be attributed to changes in either the genome or the proteome
D) Incubation temperature changes both the crocodilian genome and proteome
