The Ester linkage is the bond between a carbonyl group (C=O) and an oxygen atom (-O-). In the given figure, the ester linkage is present between the carbonyl group of the carboxylic acid (-COOH) and the hydroxyl group of the alcohol (-OH). This linkage is indicated by the letter B, as it connects the carbon atom of the carboxylic acid with the oxygen atom of the alcohol, forming an ester (-COO-). Therefore, the correct choice is B.
