Choose the correct option to change the following sentence from Assertive to Exclamatory sentence:

It is a fine weather.

What a fine weather it is!

The correct answer is Option (1) - What a fine weather it is!

The correct option to change the sentence "It is a fine weather" to an exclamatory sentence is: What a fine weather it is!"

 Explanation:

To convert an assertive sentence to an exclamatory sentence, we often use expressions like "What a" or "How" to convey strong emotion or surprise.
"What a fine weather it is!" uses "What a" to emphasize how fine the weather is, making it an exclamatory sentence.

Let's briefly examine the other options:
"It's fine weather!" is more of a statement with mild emphasis but lacks the structure of an exclamatory sentence.
"Weather is fine!" is another assertive sentence, simply restating the original in a different word order.
"How is the weather!" is a question, not an exclamatory sentence.

Thus, the correct exclamatory form is: "What a fine weather it is!"
