Question

Fill in the blanks with the appropriate question-
The reason _____ I’m writing is to tell you about a party on Saturday.
A. Because
B. For
C. Why
D. Of

Answer 1

Hint: The sentence provided needs a conjunction to relate the first phase of sentence with the second phase.
The main reason of the person writing the letter is to inform the party which indicates that a word should be chosen which fits well with the sentence.

Complete answer:
Option A- is not correct because it is grammatically wrong. Although because is used as a conjunction to join two sentences but here, the word doesn’t fit well with the sentence.
Option B- Is an incorrect option because for is generally used as a preposition and is not used as a conjunction to join sentences together to make it meaningful.
Option C- is the correct answer because why is used as conjunction and it points out well the presence of ‘reason’ in the sentence.
Option D- is an incorrect answer because of is also used as a preposition and used to indicate something belonging to or related to.
Example 1- She dreamt of being rich.
Example 2- Rohit is one of the best writers.

Hence the correct answer is option ‘C’.

Note: Why is generally used as conjunction in a sentence to define any cause, reason, purpose in it for which the incident took place.
Example- I know why you didn’t come.
Example- Rohit knows why the letter is written to him.
Some conjunctions we generally use are while, why, also, who, which, and so on.
Some examples to show the use of why as conjunction-
1. This is the reason why I came to you.
2. “Do you know the reason why she called me?” asked Snita.
