Detailed explanation-1: -Once he was observing a thin slice of cork under the microscope he found a framework similar to honeycomb-like structure. He named those structures as cells but those were actually non living cell walls. So option A is correct.
Detailed explanation-2: -Background: Important Figures in Cell History: Robert Hooke was an English scientist who looked at a thin slice of cork (oak cork) through a compound microscope. He observed tiny, hollow, room-like structures that he called ‘cells’ because they reminded him of the rooms that the monks lived in.
Detailed explanation-3: -While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells. He had discovered plant cells!
Detailed explanation-4: -Hooke detailed his observations of this tiny and previously unseen world in his book, Micrographia. To him, the cork looked as if it was made of tiny pores, which he came to call “cells” because they reminded him of the cells in a monastery.
