He looked at onion skin with his naked eyes to see cells.

|
He invented the microscope.

|
|
Under a microscope he observed box-like compartments of cork tree bark.

|
He used the microscope to observe skin cells.

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: -Micrographia Cover The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
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.
Detailed explanation-5: -Robert Hooke was the first person who observed the cells. He examined small pieces of cork obtained from the bark of trees through his simple microscope. He observed many small box-like structures and named them as cells which means little room.
