Solution

The correct option is D Assertion (A) and Reason (R) both are correct and Reason (R) is explaining Assertion (A)
The dark lines in solar-spectrum are called Fraunhofer lines. Hence, assertion is correct.

The elements in the outer atmosphere (chromosphere) of the Sun absorb the light of their characteristics wavelengths coming from Sun's inner atmosphere (photosphere). This is the cause of the existence of Fraunhofer lines.
Hence, reason is correct and is the correct reason of explanation.
