Each of the colored lines in hydrogen's emission spectrum corresponds with the C. transition of an electron from a higher energy level to a lower energy level.
An emission spectrum can be defined as the range of wavelengths, frequencies or pattern of bright lines which can be seen when the electromagnetic radiation that are emitted by an atom of a chemical compound (substance) moves through a spectrometer.
Generally, this process leads to the quantization or transfer of an electron from one energy level to another such as the transition of an electron from a energy level of higher magnitude to a lower energy level in hydrogen's emission spectrum.
