Question

In Sommerfeld’s modification of Bohr’s theory, the trajectory of an electron in a hydrogen atom is (A) a perfect ellipse (B) a closed ellipse - like curve, narrower at the perihelion position and flatter at the aphelion position (C) a closed loop on spherical surface (D) a rosette

In Sommerfeld's modification of Bohr's theory, the trajectory of an electron in a hydrogen atom is not a simple ellipse but a precessing ellipse called a rosette.
