Transform the following sentence from Assertive to Exclamatory:

The book is very informative.

What an informative book it is!

The correct answer is Option (3) - What an informative book it is!

The correct transformation of the sentence "The book is very informative." from assertive to exclamatory is:What an informative book it is!

• An exclamatory sentence expresses strong emotion or excitement, often starting with "What" or "How."
• The option "What an informative book it is!" effectively conveys enthusiasm about the book while maintaining the meaning of the original assertive sentence.
• The other options either do not properly express excitement or contain grammatical errors.
