Final answer:
The correct sentence to fix the dangling modifier is 'Known mostly as a composer of instrumentals, he added lyrics to his pieces later.' This sentence properly attaches the modifier to the subject 'he,' clarifying that he is the composer of instrumentals who added lyrics to his pieces. The correct answer is option A) Known mostly as a composer of instrumentals, he added lyrics to his pieces later.
Step-by-step explanation:
To fix the dangling modifier in the sentence, one must ensure that the modifier clearly describes the subject of the sentence. In this case, the correct sentence that rephrases the original sentence to fix the dangling modifier is:
A) Known mostly as a composer of instrumentals, he added lyrics to his pieces later.
This sentence correctly attaches the modifier "Known mostly as a composer of instrumentals" to the subject "he." Therefore, it is clear that "he" is known mostly for his instrumentals and is the one who added lyrics to his pieces later.
Other sentence options B, C, and D incorrectly attach the modifier to the subject or use an awkward sentence construction that doesn't clearly indicate who or what the modifier is describing. It's important to ensure the modifier and the noun it's meant to modify are next to each other in the sentence to avoid confusion.
