I count C. six esters.

Methyl esters don't count, because methanol is not a 1° alcohol. It has no alkyl groups attached to the carbon bearing the #"OH"# group.

There are six esters that satisfy the criteria.

Ethyl propionate

n-Propyl acetate

Isopropyl acetate

n-Butyl formate

isobutyl formate

sec-Butylformate
