GMAT Sentence Correction (SC) | Re: QOTD: Targeted toward the crucial

Since the subject is each of the dramas, it should the take singular form of the verb and should follow the "both X and Y" parallelism; ie either both from music and from modelling or from both music and modelling.
Each of the answer options, except B, has either the subject-verb agreement error or the parallelism error.
Hence correct option- B.
