Which compound is cited as smelling putrid?

Explanation:
Putrescine is the compound most closely linked to the putrid smell produced during decomposition. It’s a diamine formed when bacteria decarboxylate amino acids as tissues break down, releasing volatile amines that give a rotten, foul odor. Indole can have a strong, fecal-like odor but isn’t the classic descriptor of putrefaction here. Ammonia has a sharp, pungent smell, not the putrid rotting aroma. Water is odorless. So putrescine best represents the putrid scent described.
