7. The 3x 3 matrix corresponding to the transformation of spatial co-ordinates x--X, y>-y and z -z. (A) does not belong to the group O(3) (B) belongs to the group O(3) (C) is a continuous transformation of spatial coordinates and hence, belongs to a matrix group (D) does not have inverse and hence cannot be an element of any matrix group
