Answer:

C. A quantity that does not indicate direction.

Step-by-step explanation:

There are two types of quantities in physics:

- Scalars: a scalar quantity is a quantity which has only a magnitude, and not a direction.

Examples of scalar quantities are: mass, temperature, time, distance, speed...

- Vectors: a vector quantity is a quantity having both a magnitude and a direction.

Examples of vector quantities are: velocity, displacement, force, acceleration...

Therefore, for the question in the problem:

What is a scalar?

The correct answer is:

C. A quantity that does not indicate direction.
