Answer:A)

A shape has four sides if and only if it's a quadrilateral.

Explanation:

If a conditional statement and its converse are both true, then the statement is a biconditional statement. Biconditional statements can be written using the phrase “if and only if.” For example, a polygon is a hexagon if and only if it has six sides.
