a) stationary
b) moving towards Earth
c)moving away from earth
d) information is incomplete​

Answer 1

answer is option (b).....

Answer 2

Answer:

In the Shift of wavelength of light emitted by star is towards violet then this shows that star is Moving towards Earth.

Explanation:

Shifting to the ultraviolet region reveals that the apparent wavelength has decreased. The peak wavelength of a star is the wavelength at which it emits the most light. This star has a peak wavelength of $4000$ Angstroms, as shown in the diagram on the right. Shifting to the violet region reveals a decrease in apparent wavelength. As a result, the source is moving towards the earth.
