Answer»

The correct choice is (a) EXACTLY 90°

Easy explanation: When a four sided POLYGON has its all SIDES EQUAL in LENGTH it is a square. Any square has it’s angles =90°. Hence the answer would be 90°. Here the other options won’t be accurate. For example if a student selects the option 90° or any acute angle it would be partially correct because in a square the angles are always right angles.
