Answer: Vector.
- A Scalar
- B Vector
- C Tensor
- D Matrix
Correct answer: B. Vector
Explanation: A vector has both magnitude (size) and direction, unlike a scalar which has only magnitude.
Triangle law of vector addition: placing vector b at the head of vector a, the diagonal from the start to the final head gives the resultant a + b.
