What is a step michelangelo used in creating
in-the-round sculpture?
he used various chisels to shape
the figure.
he used a soft cloth to polish the
sculpture.
he began with a large block of
plaster.
he used a drill to remove stone
from the block.

He used various chisels to shape the figure.

Explanation:

I'm not 100% sure this is true but I remember reading about his works and how most sculptors created their works. I do know sculptors (especially back then) used chisels to shape the figure's body and other areas. So I do believe the first one is the answer you are looking for.

Sorry if anything is wrong, but let me know how it goes if you didn't already answer :)
