The correct option is D (i) and (ii)
(i) and (ii) are angles that are less than 90∘. So, they are acute angles.
(iii) is a right angle.
(iv) is greater than a straight angle and less than a full circle. So, it is a reflex angle.
(v) is greater than a right angle and less than a straight angle. So, it is an obtuse angle.
