Material in Solar Spicules Is Ejected Out of the Sun $\alpha$

Material in solar spicules is ejected out of the Sun at typical speeds of 20 km/s. What would be the observed wavelength of the Balmer H $\alpha$ hydrogen spectral line emitted by this gas, compared to that from stationary solar material?

A) There will be no shift, because the light is emitted by hydrogen gas in both the spicule and the stationary solar material.
B) 0.000067 nm shorter than the H $\alpha$ from the stationary solar material
C) 0.044 nm longer than the H $\alpha$ from stationary solar material
D) 0.044 nm shorter than the H $\alpha$ from stationary solar material
