Question

1. which of the following sets is considered a null set?

• mugs with handles
• dogs with four legs
• weeks with eight days
• books with pages

Explanation:

A null set (empty set) contains no elements. Mugs often have handles, dogs typically have four legs, and books usually have pages, so those sets have elements. A week is defined as seven days, so there are no weeks with eight days, making that set empty.

Answer:

C. weeks with eight days
