A. Whether
B. Which
C. Why
D. What

Answer 1

Hint: The sentences that we read and study in grammar are made up of a few, specific elements that help in forming the basic meaning of the sentence. We have read and studied about the subject, the object, the verb and the helping verbs that accompany verbs. We often tend to miss a small yet important element that combines two words, phrases or clauses. This element is the ‘conjunction’.

Complete step by step answer:
1. In order to find the word which will be the appropriate option to fill in the blank, we have to check each option one by one so that we can detect the correct option.
2. The first option ‘whether’ is a conjunction that is used to link two or more sentences. It is described as a word that expresses a doubt or choice between alternatives. When this word is added to the sentence given in the question as we can see that it meaningfully completes the sentence.
The sentence: “I doubt whether everybody knows how to solve the housing problem in Turkey”
shows the uncertainty of the speaker. Thus, it is the correct answer.
3. If we look at option B ‘which’, option C ‘why’ and option D ‘what’, we can see that these three words are words that ask questions also known as interrogative words. No question is being made here in this sentence. Thus, option B, option C and option D are not correct.

Thus, Option A is correct.

Note:
Sentences are formed by a few grammatical elements that bring out their basic meaning. These elements can be the subject, object, verb and helping verbs. They form phrases and clauses which are connected by words that are known as conjunctions.
