Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. who
- The word "who" is used to refer to a person, which is appropriate here since Sandra is a person.
- "Who" is the correct relative pronoun to refer to a person. It connects the clause "I thought was my friend Sandra" to the noun "someone" and specifies that "someone" is a person.
