Explanation:

Step1: Recall properties of rhombus

A rhombus has all - sides congruent and opposite - sides parallel.

Step2: Recall properties of rectangle

A rectangle has opposite - sides parallel and all angles are right angles.

Step3: Determine when rhombus is rectangle

A rhombus becomes a rectangle when its angles are right angles because then it satisfies the angle - property of a rectangle while still having the side - properties of a rhombus.

Answer:

D. When its angles are right angles
