b)3 parts

Step-by-step explanation:

Answer 2

$\:$

A circle can divide a plane into at most 2 parts: the interior of the circle and the exterior of the circle.

However, if the circle intersects itself (i.e., it has a self-intersection), then it can divide the plane into more than 2 parts. The number of parts would depend on the number of self-intersections, but this is not a common occurrence and not typically considered for this question.

Therefore, the correct answer is (a) 2 parts.
