In the Eighteenth Century,Sir William Herschel Used Star Counts in Regions

In the eighteenth century,Sir William Herschel used star counts in regions of the sky along the Milky Way to estimate the position of the center of the Galaxy.He incorrectly concluded that the Sun was close to the Galaxy's center.The reason for this erroneous conclusion was that

A) Herschel counted all stars in each star field,including many that were outside our Galaxy,thus confusing the distribution.
B) the redshift of the more distant stars made them invisible to Herschel.
C) he had no knowledge of the large quantity of dust between stars,which obscured the more distant regions of the Galaxy.
D) he mistook globular clusters for stars,and those are distributed uniformly around the Sun.
