Explanation:

Ser is used in a simple way, to talk about WHAT something is (permanent state). To describe characteristics that are an essential part of the thing we’re talking about.

Estar is used to talk about HOW something is, so we use it for conditions, locations, emotions, and actions (temporary states).

The parents being hungry is not a permanent condition. It's temporary. Thus, it is estar that we need to use, which is answer B.
