a. an angle measuring more than 90°
b. an angle measuring more than 90° and less than 180°
c. an angle measuring more than 0° and less than 90°
d. an angle measuring less than 0°

Explanation:

An acute - angle is defined as an angle whose measure is greater than 0° and less than 90°. Option A describes an obtuse or reflex angle, option B describes an obtuse angle, and option D is not a standard positive - measured angle in basic geometry.
