Solution

The correct option is A amino acids and glucose
Na+ ions facilitates the absorption of glucose and amino acids. Secondary active transport is one of the two main types – co transport(e.g glucose and some amino acids along with inward pushing of Na+) and counter transport ( Ca2+ and H+ import outwardly as excess Na+ passes inwardly).
