Correct Answer - Option 2 : make him clear
The correct answer is 'make him clear'.
- In the given sentence, the use of the personal pronoun 'him' is incorrect.
- A personal pronoun refers to a specific person or object or group of things directly.
- The reflexive pronoun 'himself' should be used in place of the personal pronoun 'him'.
- A reflexive pronoun expresses a noun when the subject's action affects or influences the subject itself.
Hence, the correct answer is option 2.
Correct Sentence: He spoke slowly in order to make himself clear.
