If $r_p, v_p, L_p$ and $r_a, v_a, L_a$ are radii,velocities and angular momenta of a planet at perihelion and aphelion of its elliptical orbit around the Sun respectively,then
- A$r_p > r_a, v_p > v_a, L_a > L_p$
- B$r_p < r_a, v_p > v_a, L_a = L_p$
- C$r_p > r_a, v_p < v_a, L_a = L_p$
- D$r_p < r_a, v_p < v_a, L_a < L_p$
