none of these is correct

Detailed explanation-1: -Insulin: decreases blood glucose through increased expression of GLUT4, increased expression of glycogen synthase, inactivation of phosphorylase kinase (thus decreasing gluconeogenesis), and decreasing the expression of rate-limiting enzymes involved in gluconeogenesis.
Detailed explanation-2: -Insulin helps blood sugar enter the body’s cells so it can be used for energy. Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too.
Detailed explanation-3: -Each of the hormones has distinct functions. Glucagon increases blood glucose levels, whereas insulin decreases them. Somatostatin inhibits both, glucagon and insulin release, 6 whereas PP regulates the exocrine and endocrine secretion activity of the pancreas.
Detailed explanation-4: -The Role of Glucagon. Glucagon, a peptide hormone secreted by the pancreas, raises blood glucose levels. Its effect is opposite to insulin, which lowers blood glucose levels.
