It is a CR question from veritas prep..need explanation

The German baroque composer J.S. Bach notated most of the melodic lines in his works, leaving little room for interpretation by performers. An unnamed baroque composition was recently discovered in a church in Germany. Since the composition contains numerous notated melodic lines, it is probably a work of J.S. Bach.

Which one of the following contains a pattern of flawed reasoning most similar to that in the argument above?

A) Most baroque composers wrote for a single instrument, such as organ or harpsichord. Since The German Organ Mass was originally written for the organ, its composer probably always wrote for the organ.

B) In baroque musical works, the single most common subject is religion, so the single most common subject in all baroque art forms is also religion.

C) Works of art in the baroque period were mostly commissioned by patrons, so the baroque musical composition Chromatic Fantasia and Fugue was probably commissioned by a patron.

D) The anonymously composed keyboard piece Tune for the Woodlark is probably a baroque composition since it is written for the harpsichord, which was the most common keyboard instrument employed by baroque composers.

E) Since baroque musical compositions were mostly concerned with religious subjects, the baroque composer Charles Racquet, whose works are now lost, probably composed music mostly concerned with religious subjects.

Please explain why 'D' is the correct one

First and foremost, this is not a style of question that you are likely to find on the GMAT. This looks like something out of an LSAT practice test, and practicing for the LSAT is probably not the best use of your time if you are preparing for the GMAT.

That said, the logical fallacy in the argument is that when a specific thing (Bach's music) falls under a larger category (noted lines), anything in the larger category is probably from the more specific category.
