Answer 1

Hint: A complete sentence is correct only if you are applying grammar rules correctly. Tenses are important in English grammar. Tenses of a verb are used to define the particular state or situation of something. In English, there are three main tenses- present, past, and future.

Complete answer:
In the above question, we are talking about giving thanks to the person who has written the piece of music.
We have four different options here to correct the underlined part of the question if it's incorrect. From the option, we notice that we have two groups of options one that has ‘whomever’ in the option and one that has ‘whoever’ in the option.
Firstly, let’s ask one question to understand which one either ‘whoever’ or whomever’ is correct. The question is ‘who wrote the piece of music?’-He/ him wrote it? The answer is ‘He wrote it’. Therefore, we require ‘whoever’ and not ‘whomever’.
Here, we omitted the options which have whomever in options. So, option (B) and (c) are eliminated.
We have two complete sentences and we need to join those two complete sentences. So, here option(E) is eliminated because it has a comma in last which is not used to join two complete sentences and the second sentence supports the first.
Now we left with option (A) and (D), A is the most direct and suitable. Therefore, option(A) is the correct answer.

Note:
In English grammar rules should be applied correctly. Tense plays an important role in forming a sentence. There are three main tenses-present, past, future. In the above question, we needed to understand who wrote the piece of music. He wrote it. So, the correct opinion with whoever and which goes most suitable with the question is correct.
So, the correct answer is an option (A): I would like to thank whoever it was that wrote that piece of music-
I would like to thank whoever it was that wrote that piece of music: it has given me so much pleasure.
