Answer:

C

Explanation:

mass is a scalar quantity, number of anything is also a scalar quantity, since it lacks direction, and wind velocity is a vector quantity

The given quantities are classified as vector and scalar quantities;

  • mass of an object (scalar)
  • the number of leaves (scalar)
  • wind velocity (vector)

Vector quantities are those quantities that have both magnitude and direction. Examples include the following;

  • velocity (m/s)
  • acceleration (m/s²)
  • force (N)
  • weight (N)

Scalar quantities are those quantities that have only magnitude but no direction. Examples include the following;

  • speed
  • distance
  • mass
  • work, etc

Thus, from the explanation above, we can classify the given quantities as follows;

  • mass of an object (scalar)
  • the number of leaves (scalar)
  • wind velocity (vector)
