Choose the option with the correct punctuation marks-
What a beautiful painting it is
a. What a beautiful painting it is.
b. What a beautiful painting it is?
c. What a beautiful painting it is!
d. What a beautiful painting, it is.

Hint: Punctuation marks are the marks which are used in writing to separate sentences and their elements and to clarify meaning.

Complete answer:
Marks such as a full stop, comma, or question mark, exclamation mark, etc. are punctuation marks. They are vital to disambiguate the meaning of sentences. The rules of punctuation vary with language, location, register and time and are constantly evolving.
Now, we will examine all the given options to find out the correct answer:
- Option ‘a' has a full stop in it. We can clearly see that the given sentence is not a general statement and only a full stop will not work here. So, this is not the correct answer.
- Option ‘b’ has a question mark. A question mark is used in an interrogative sentence, a sentence which is asking a question. But, here, no question is asked. A strong emotion of excitement is shown in the given sentence, which doesn’t match the context of this option. So, this is not the correct option.
- Option ‘c’ has an exclamation mark. Such marks are used to end an exclamatory sentence, when someone expresses a great sense of joy and excitement. Here, in the given sentence, the same emotion is being conveyed. So, this is a correct option.
- Option ‘d’ has a comma and a full stop. Both of these are generally used in a normal statement, but this isn’t one. So, this is also the wrong option.

> As we have analysed all the given options, we can easily figure out the correct option. Here, the correct form of the given sentence is option ‘c’. Hence, the correct answer is with the exclamation mark, “What a beautiful painting it is!”

Note: The given sentence may start with “what”, this doesn’t mean that it will end with a question mark(?).
