Answer:
C) vector
Step-by-step explanation:
A vector magnitude is that which, in addition to a numerical value and its units (module), we must specify its direction and magnitude.
The choice of a scalar or vector to represent a physical magnitude depends on the nature of it; if we are describing the temperature of a room, the density of a body, its mass... we'll need to represent them by a number. On the contrary, when we work with magnitudes such as force, speed, acceleration, momentum, electric field, etc., we will use vectors, because they have direction also
