Vector product is not commutative , i.e., begin mathsize 14px style A with rightwards arrow on top space cross times B with rightwards arrow on top space not equal to B with rightwards arrow on top space cross times space A with rightwards arrow on top space end style
If begin mathsize 14px style A with rightwards arrow on top space cross times B with rightwards arrow on top space space equals space B with rightwards arrow on top space cross times space A with rightwards arrow on top space end style, then vectors begin mathsize 14px style A with rightwards arrow on top end style and begin mathsize 14px style B with rightwards arrow on top end style are either parallel or anti-parallel
so that begin mathsize 14px style A with rightwards arrow on top space cross times B with rightwards arrow on top space space equals space B with rightwards arrow on top space cross times space A with rightwards arrow on top space equals space 0 end style
Hence the answer to be chosen is (c) π
