Which quantity has magnitude but no direction?

Explanation:
Scalar quantities are described by magnitude alone, with no direction. This means they convey only how much of something there is, not which way it’s pointing. In contrast, vector quantities carry both magnitude and direction, so direction is an essential part of them. Many common scalars exist—mass, temperature, distance, and speed—all have magnitude but no inherent direction. The term that names this whole category—quantities with only magnitude—is scalar quantities, making it the correct choice. (Speed and distance are examples of scalars, but the question targets the category rather than a specific example.)
