Choose the correct options to fill in the blanks questions (1-4):

I don't know who —— the chair.

খ broke.

Complete Sentence:

"I don't know who broke the chair."

Explanation:

• "Broke" is the past tense of the verb "break," which fits the context of the sentence as it refers to an action that has already occurred.

• The other options do not fit grammatically in this context:

  • "Breaks" (ক) is present tense and does not fit after "who."

  • "Breaking" (গ) is a gerund and does not fit the structure of the sentence.

  • "Break" (ঘ) is the base form, which is also not suitable after "who."
