Explanation Reason for the correct statement: Option a. is given as “precentral gyrus”. The frontal lobes consist of cortical region that regulates motor functions. The primary motor cortex is located in the precentral gyrus of the frontal lobe. Hence, the primary motor cortex is located in the precentral gyrus. Hence, option a . is correct. Reasons for incorrect statements: Option b. is given as “postcentral gyrus”. The post central gyrus is located in the parietal lobe and this does not consist of primary motor cortex. Hence, option b. is incorrect. Option c...
