Solution

The correct option is B b) Statement-1 is true, Statement-2 is true , Statement-2 is a correct explanation for statement-1
The scalar product of any two vectors $\to A$ and $\to B$ is given by $\to A . \to B = A B c o s θ$ where $θ$ is angle between $\to A$ and $\to B$ .
Now, when two vectors are perpendicular to each other then $θ = 90^{0}$ which implies $\to A . \to B = A B c o s 90^{0} = 0$ .
Therefore, statement 1 and 2 are true statement 2 is explanation of statement 1.
