Solid state physics

A B Refer to the figure above. If the z-axis points out of the plane of the paper towards you, the triangle marked A' can be transformed (and suitably re-positioned) to the triangle marked 'B by (a) rotation about x-direction by r/2, then rotation by -r/2 in the yz-plane b) rotation about z-direction by /2, then reflection in the yz-plane (c)reflection in the yz-plane, then rotation byr/2 about z-direction (d) reflection in the xz-plane, then rotation by - r/2 about z-direction
