If `vec u , vec nu`, and `vec w` are non coplanar vectors and p,q are real numbers, then the equality `[3 vec u p vec nu p vec w]-[p vec nu vec w q vec u]-[2 vec w q vec nu q vec u] = 0` holds for

Options

A. exactly one value of (p,q)
B. exactly two values of (p,q)
C. more than two but not all values of (p,q)
D. all values of (p,q).

Answer

A
