Select the most appropriate option to fill in blank number 2.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. has.
Context: The blank is part of a sentence that talks about a recent trend in heart-attacks among young Indians. The blank (2) must take a verb that agrees with the subject and shows that the trend continues into the present.
Analysis of the given options:
-
have been: present perfect plural; incorrect as the subject is singular
-
had: past perfect; does not suit the “recently” + present relevance
-
has: present perfect singular; grammatically correct
-
have: incorrect as it lacks a past participle after it
Correct word: has
Reason:
The subject is “The number”, which is singular, not “heart-attacks”. So, it takes a singular verb: has.
Also, “has increased” is the present perfect tense, which is appropriate with the word “recently” to show a trend continuing to the present.
Hence, the chosen option is correct.
