Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. but I don’t know.
Error concept: Incorrect verb form
What is wrong: The sentence uses don’t knew, which incorrectly mixes present tense auxiliary don’t with past tense knew.
Grammatical concept: Present tense auxiliary verbs must be followed by the base form of the main verb.
Incorrectness of the concept in context: “don’t knew” is ungrammatical; it should be don’t know to match present tense.
How to correct: Replace don’t knew with don’t know.
Correct phrase/ correction: She said she would join us later, but I don’t know if she will make it on time.
Final sentence: She said she would join us later, but I don’t know if she will make it on time.
Hence, the chosen option will be correct.
