# Please solve it.

As we know,

$\left(\overrightarrow{A}\times \overrightarrow{B}\right)=-\left(\overrightarrow{B}\times \overrightarrow{A}\right)\phantom{\rule{0ex}{0ex}}So\phantom{\rule{0ex}{0ex}}\left(\overrightarrow{A}\times \overrightarrow{B}\right)+\left(\overrightarrow{B}\times \overrightarrow{A}\right)=0\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}$

Hence they are vectors of equal magnitude but opposite direction.

Thus the angle between then is 180°

So correct option is c.Regard
