I'm not sure but but i think the answer will be:
A. additive genetic variance times the selection differential.
Explanation:
When blood glucose levels increase above set point, the hormone insulin, which is produced in the beta cells of the Islets of Langerhans in the pancreas, is secreted into the bloodstream.
