Solution

The correct option is C $π$
We know that , $\to A \times \to B = - (\to B \times \to A)$
But, if the angle between $\to A$ and $\to B$ is integer multiple of $π$ ,
Then only $\to A \times \to B = \to B \times \to A = 0$
Hence, the angle between $\to A$ and $\to B$ is $π$ according to options.
