Which of the following statements are true ? (A) The subsidiary quantum number ll describes the shape of the orbital occupied by the electron. (B) [figure: two lobes along the xx-axis with the yy-axis through the origin] is the boundary surface diagram of the 2px2p_x orbital. (C) The ++ and −- signs in the wave function of the 2px2p_x orbital refer to charge. (D) The wave function of 2px2p_x orbital is zero everywhere in the xyxy plane. Choose the correct answer from the options given below :

The figure, in words

Statement (B) contains a diagram: two circular lobes touching at the origin along the x-axis, y-axis vertical through the origin, with a z-axis line drawn diagonally; labelled boundary surface diagram of the 2p_x orbital.
