Assertion (A) : The Balmer series in hydrogen atom spectrum is formed when the electron jumps from higher energy state to the ground state. Reason $\displaystyle (R)$: In Bohr's model of hydrogen atom, the electron can jump between successive orbits only.
Official answer
(D)
Both Assertion (A) and Reason (R) are false.
