The emission spectra is produced when
A
electrons release energy as they move to their excited state.
B
electrons absorb energy as they move to their excited state.
C
electrons release energy as they return to the ground state.
D
electrons absorb energy as they return to the ground state.
Explanation: 

Detailed explanation-1: -Atomic emission spectra are produced when excited electrons return to the ground state. When electrons return to a lower energy level, they emit energy in the form of light.

Detailed explanation-2: -The energy electrons emit when returning to the ground state is electromagnetic radiation, or EMR.
