Question

Which receptor, when activated, most likely prompts the production of saliva?

Answer:

Taste receptors.

The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.
