Transform the following sentence from exclamatory to assertive.

Hint: A sentence's transformation is all about altering its form without altering its meaning. For instance, we can turn an exclamatory phrase into an assertive phrase or vice-versa. We may transform simple sentences into complicated or compound sentences as well.

Complete step by step answer:
We may turn a simple phrase into a compound phrase or a complex phrase. Typically, this is accomplished by extending a word or phrase into a clause. We may transform a complex or compound sentence into a simple sentence in the same way. This is achieved by lowering a clause into a phrase or word.
A statement that conveys intense emotion or excitement is rendered by an exclamatory phrase. The given exclamatory sentence is: Alas! +subject +verb + clause.
The sentence which declares or asserts a statement, feeling, opinion, incident, event, history, or anything is called an assertive sentence. An assertive sentence ends with a period (.). Assertive sentences can be either affirmative or negative.
The form of the assertive sentence is: It is a pity + subject + verb +clause when a sentence of exclamatory form is converted to assertive. Option A is the choice that follows this structure, so it's right.

So, the correct answer is “Option A”.

Note:
To answer these types of questions improve your concepts about the transformation of the sentences. While transforming sentences, it has to be kept in mind that the meaning or sentiment of the given sentence does not change. If the meaning of a sentence changes, then it is not called sentence transformation.
