Statement-I: The cross product of a vector with itself is a null vector.
Statement-II: The cross product of two vectors results is a vector quantity.

View answer and explanation

Correct option: A

Statement-I is true and statement-II is true

Option A (Statement-I is true and statement-II is true) is correct because the cross product of a vector with itself is indeed a null vector, and the cross product of two vectors results in a vector quantity.
