Answer: choice b

Letter A with a horizontal line over top.

Step-by-step explanation

The shaded region consists of everything outside of circle A. We call this the complement of set A, i.e. it's the complete opposite of set A.

The notation for the complement is
A^c or we could write
\overline{A} to mean the same thing. Other textbooks may use other notation.
