To determine the answer to this question, we need to understand the definition of speed and how it differs from other concepts like acceleration, velocity, and mass.

Speed is a measure of how quickly an object is moving, regardless of the direction. It is a scalar quantity, meaning it only has magnitude and not direction. This means that speed does not specify direction.

Acceleration, on the other hand, is the rate at which an object's velocity changes over time. Velocity, similar to speed, measures the rate at which an object's position changes. However, velocity is a vector quantity as it includes both magnitude (speed) and direction.

Mass, another concept mentioned in the question, is a measure of the amount of matter in an object. It is unrelated to speed, acceleration, velocity, or direction.

Now, looking at the options provided, we can see that the correct answer is "Direction". Speed does not specify direction as it is a scalar quantity that only indicates how fast an object is moving, not in which direction it is moving.
