  1. Radian
  2. Steradian
  3. Degree
  4. Lux

Answer: B. Steradian

The solid angle is measured in steradian.

Solution

Radian is a unit of plane angular measurement that is equal to the angle of centre of circle subtended by an arc of that circle whose length is equal to the radius of that circle or approximately 57.3 degrees.

Steradian is the standard unit of solid angle. It is used in 3-D geometry. A steradian is defined as conical in shape. The solid angle is measured in steradian.

Degree is a unit of plane angular measurement of plane angle in which 360 degrees is one full rotation.

Lux is a unit of measurement of illuminance.
