`veca.(vecbxxvecc)` is called the scalar triple product of `veca,vecb,vecc` and is denoted by `[veca vecb vecc]. If veca, vecb, vecc` are cyclically permuted the vaslue of the scalar triple product remasin the same. In a scalar triple product, interchange of two vectors changes the sign of scalar triple product but not the magnitude. in scalar triple product the the position of the dot and cross can be interchanged privided the cyclic order of vectors is preserved. Also the scaslar triple product is ZERO if any two vectors are equal or parallel. `[veca+vecb vecb+vecc vecc+veca]` is equal to (A) `2[veca vecb vecc]` (B) `3[veca,vecb,vecc]` (C) `[veca,vecb,vecc]` (D) 0
