Nsome organisms, the primary function of a gene in a cell is to participate in regulating the body as a whole rather than responding to the cell's immediate environment. these organisms would be diploid. multicellular. prokaryotic. bacterial.

Option B, Multicellular

Explanation:

Prokaryotes as well as bacteria's are unicellular organism in which genes cater specific cellular requirement. In case of multi-cellular species, cell differentiate to form tissues and hence organs. Now these organs perform basic functions to keep this organism alive. Therefore, in multi celled organism a gene deals with the body as a whole. It does not respond to individual cell requirement.   In doing so, individual cell requirements are also full-filled.

Hence, option B is correct
