correct ans is pa[5].
after executing the statement pa=a;pa will point to the array a.now array a has 2 pointers which are a and other is pa.we can use subscript operator for pointers also when it points to an array.
so pa[5] will give 6th value in that array.

You did not read the question correctly. Which option is WRONG.

And that is d), since you deference pa before the incrementation, this is likely going to give you an invalid memory access
