Vector is quantity that ------.
Correct answer: D. All of the above
- A. Has direction
- B. Has magnitude
- C. Follow rules of vector addition
- D. All of the above
Explanation
A vector is defined as a quantity that has both magnitude and direction. In addition to these fundamental properties, vectors also follow specific rules for addition that allow them to be combined in a consistent manner. Option A is incomplete because it only mentions direction. Option B is similarly inadequate, as it only refers to magnitude. Option C, while accurate in its description of vector addition, does not fully capture the essence of what a vector is, as it neglects to mention magnitude and direction. Therefore, the correct answer is Option D, which states that a vector possesses all these properties.

About Addition of Vectors
Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
