In option A , can be also written as . But it doesn't match with the other expression given. Hence they are not equivalent expressions.In option B , can be also written as . But it doesn't match with the other expression given. Hence they are not equivalent expressions.In option C , can be also written as . Hence they are equivalent expressions.In option D , can be also written as . Hence they are equivalent expressions

Thus , Option C & D are correct.
