Answer 1

C

Explanation:

Rules of multiplying numbers with positive and negative signs are the following:

• (-)(-) = +
• (+)(+) = +
• (-)(+) = -
• (+)(-) = -

This means that there should be an odd number of negative numbers in a product to get a negative number.

A will be positive.

B will be positive.

C will be negative.

D will be neither since 0 is its product
