D. "It is unclear why"

Answer 1

The phrase that uses synecdoche is:

B. "He often snuck away from the Benedictine eye to explore"

In this phrase, "the Benedictine eye" represents the vigilance or watchfulness of the Benedictine nuns, using a part (the "eye") to refer to the whole (the nuns' supervision or control).
