Question

Fill in the blank with the correct form of verb : 
You had better _____ your hands before you eat.

Accepted Answer

The correct answer is Option 4: **wash**.

Here's why:

*   **"Had better" is a modal idiom that is always followed by the base form of the verb (the infinitive without "to").** The phrase "had better" expresses advice or a strong recommendation. It implies a potential negative consequence if the advice is not followed. Therefore, the verb following "had better" must be in its simplest form.

Now, let's examine why the other options are incorrect:

*   **Option 1: been washing** - This is incorrect because "had better" cannot be followed by "been washing." "Been washing" is a present perfect continuous form, and it doesn't fit the grammatical structure required after "had better."

*   **Option 2: washing** - This is incorrect because "had better" is not followed by the gerund form of the verb (the -ing form). The structure requires the base form.

*   **Option 3: washed** - This is incorrect because "had better" is not followed by the past participle form of the verb. The past participle is used in perfect tenses or passive voice constructions, neither of which are appropriate after "had better."

Therefore, only **Option 4: wash** correctly follows the grammatical rule that "had better" must be followed by the base form of the verb. The complete sentence, "You had better wash your hands before you eat," is grammatically correct and conveys the intended meaning of a strong recommendation.
