Question

Fill in the blank with the most appropriate word.
Petroleum ____ are getting more and more expensive everyday.

• A. produces
• B. products
• C. production
• D. productivity

Answer 1

The correct option is B products

The given sentence does not have a subject. Thus, the answer must be a noun/pronoun which will become the subject. On the other hand 'are' is a plural verb, so, the word to be filled in the blank must be a plural subject in order to complete the subject-verb agreement.

Option A is incorrect. 'produces' can be a noun but, it means 'yield'. 'yield' can become more or less, it cannot become expensive or cheap. Thus, the noun does not agree with the adjective and so, 'produces' is not the best fit for the blank.

Option B is correct. 'products' is a plural noun. Also, 'products' are things that can become expensive. Thus, it fits in the blank and is the correct answer.

Option C is incorrect. 'production' is a singular noun and not a plural one. Thus, it does not justify the presence of 'are' and makes the sentence grammatically incorrect.

Option D is incorrect. 'productivity' is a singular noun and not a plural one. Thus, it does not justify the presence of 'are' and makes the sentence grammatically incorrect.
