Which of the following is a vector quantity?

In physics, a vector quantity is a physical quantity that has both magnitude and direction. Area is an example of a vector quantity because it has both magnitude (e.g., square meters) and direction (e.g., the orientation of the area in three-dimensional space).

The other options are not vector quantities:
Option B: Power is a scalar quantity because it has magnitude but no direction.
Option C: Electric Current is a scalar quantity. While it involves the motion of charged particles, it is described by magnitude only.
Option D: Energy is a scalar quantity. While energy can be associated with physical processes, it is also described by magnitude only.
Option E: None of these is not the correct answer because, as explained, Option A (Area) is indeed a vector quantity.

So, the correct answer is Option A: Area, as it is a physical quantity that possesses both magnitude and direction, which are characteristics of vector quantities.
