The correct answer is Option B: 'It is treated as vector for small rotations.' This is accurate because angular displacement, which indicates the angle of rotation about an axis, is indeed a vector quantity, encompassing both direction and magnitude. In contrast, Option A is incorrect because angular displacement can decrease or remain constant depending on the rotation direction. Option C is misleading since angular displacement is not a scalar; it is fundamentally a vector. Finally, Option D is incorrect as angular displacement is measured in radians, not in meters, which are units of linear distance.

This statement is false because angular displacement can decrease if an object rotates in the opposite direction. It is not guaranteed to always increase over time.

This statement is true because angular displacement is a vector quantity, which means it has both magnitude and direction. For small rotations, it can be effectively treated as a vector.

This statement is incorrect because angular displacement is not a scalar; it is a vector quantity that includes both magnitude and direction.

This statement is incorrect; angular displacement is measured in radians, not meters, as it refers to the angle through which an object rotates.
