Respuesta :
D, sensuous drowsiness. Indolently is being used to describe how he puffed. Steamer chair, another pipe, and favourite brier are all nouns, not descriptions so offer no insight.
The answer is D: sensuous drowsiness. The picture in the passage is of Rainsford denying that he is sleepy and intends to smoke another pipe. When he is on the afterdeck, that reclining chair invites him to just relax, no effort is required to enjoy his favorite brier, indolently. It felt so at ease and pleasantly to get caught by this drowsiness of the night.
