Select the most appropriate option for blank number 4.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. which.
- Relative pronouns are used at the beginning of an adjective clause (a dependent clause that modifies a noun). The three most common relative pronouns are who, which and that. Who has two other forms, the object form whom and the possessive form whose. Who and whom are used mainly for people.
- As the noun is "Compound" we need to use "Which" as our relative pronoun.
Hence, the chosen option will be correct.
