Question

Fill in the blank:
I __________ him since my childhood.

• A. know
• B. has been knowing
• C. have known
• D. had been known

Hint:

Use the present perfect tense ("have known") to describe actions that started in the past and continue into the present.

Answer 1

The Correct Option is C

Step 1: Understand the tense and time frame.
The sentence talks about an action that started in the past and continues into the present. We need to use the present perfect tense, which is formed with "have/has + past participle." Step 2: Evaluate the options.
% Option (1) know: Incorrect. The simple present tense is not appropriate here as the action has been ongoing since childhood.
% Option (2) has been knowing: Incorrect. The verb "know" is not used in the continuous tense in this context.
% Option (3) have known: Correct. This is the present perfect tense, which is used for actions that started in the past and continue to the present.
% Option (4) had been known: Incorrect. This is the past perfect continuous tense, which does not fit the sentence's meaning.
