Some Types of Fish Can Generate an Electric Field Around

Some types of fish can generate an electric field around their body to communicate with other individuals of the same species (like vocalization in birds) . The electric field is generated by cells called electrocytes, which are modified muscle cells. This reflects the fact that:

A) physiological mechanisms are the basis of behaviors.
B) behaviors are influenced by the environment.
C) there is a genetic basis to many behaviors.
D) behaviors develop over time.
