Question

Put the verb in the correct form : 
It _____ since early morning.

Accepted Answer

Explanation:

1. **Option 1: "has been raining"**  
   This option is correct because it uses the present perfect continuous tense, which is appropriate for describing an action that started in the past and is still continuing in the present. The phrase "since early morning" indicates that the action began at a specific point in the past and is ongoing, making the present perfect continuous tense the most suitable choice. The structure "has been raining" correctly combines the auxiliary verb "has" with the past participle "been" and the present participle "raining," which is the standard form for this tense when the subject is singular or uncountable, like "it" in this case.

2. **Option 2: "have been raining"**  
   This option is incorrect because it uses "have" instead of "has." The subject "it" is singular, and in English grammar, the auxiliary verb "has" is used with singular third-person subjects in the present perfect continuous tense. "Have" is used with plural subjects or with the pronouns "I" and "you," making this option grammatically incorrect for the given sentence.

3. **Option 3: "had rained"**  
   This option is incorrect because it uses the past perfect tense, which is used to describe an action that was completed before another action in the past. The sentence does not provide any context for a subsequent past action, and the phrase "since early morning" suggests an ongoing action rather than a completed one. Therefore, the past perfect tense is not appropriate here.

4. **Option 4: "is been raining"**  
   This option is incorrect because it is not a grammatically valid construction in English. The combination "is been" does not exist in standard English grammar. The correct form for expressing ongoing actions in the present would be "is raining" (present continuous) or "has been raining" (present perfect continuous), depending on the context. Since the sentence indicates an action that started in the past and continues to the present, "is been raining" is not suitable.

In conclusion, Option 1, "has been raining," is the correct choice because it accurately reflects the ongoing nature of the action from the past to the present, as indicated by the phrase "since early morning."
