Best Answer Explained in Below-:

The sentence "May Allah help you" is classified as an optative sentence. Optative sentences express wishes, hopes, or desires, conveying the speaker's longing for something to happen. In this case, the speaker is expressing a desire for divine assistance or support for the person they are addressing. The word "may" indicates a wishful tone, as it is often utilized in the construction of such sentences to suggest a hope that something good will occur.

While imperative sentences issue commands or requests and assertive sentences declare facts, the distinctive feature of optative sentences is their focus on wishes rather than actions. They often include the words "may" or "would," which indicate a longing for a particular outcome. In contrast, exclamatory sentences convey strong emotions but do not primarily express wishes or desires.

In summary, "May Allah help you" is characterized by its expression of hope or desire for divine aid, making it a clear example of an optative sentence.
