. . . . . . . . know computer operating among us.

Solution (By Examveda Team)

The question requires choosing the correct quantifier to precede "know computer operating among us." A quantifier determines the quantity of a noun.

Option A: One of
"One of" is used before plural nouns. It indicates a single person or thing selected from a group. For example, "One of the students is absent." This option would be grammatically correct if followed by a plural noun like "the people," "the students," or "the employees". In this case, it would create the sentence, "One of us knows computer operating". However, it needs to be accompanied by a plural noun phrase which is not present in this context. Hence, grammatically, while not fully incorrect, this is not a proper usage.

Option B: A few
"A few" is used with countable nouns and indicates a small number. For instance, "A few students passed the exam." However, "a few" requires a plural noun. This means that the sentence would only be correct if rewritten in plural form to agree with the quantifier: "A few of us know computer operating." However, the structure of the sentence in the given question is singular. Thus, it makes the sentence grammatically incorrect.

Option C: Jayesh
"Jayesh" is a proper noun, and it refers to a specific individual. This is the correct option because it correctly identifies a single person who possesses the knowledge of computer operating. The sentence "Jayesh knows computer operating" is grammatically correct.

Option D: A little
"A little" is used with uncountable nouns. For example, "I have a little money." "Know computer operating" is not an uncountable noun. It expresses a skill or knowledge. Therefore, "a little" is not the appropriate quantifier to use here. It's grammatically incorrect in this context.

Therefore, the correct answer is C: Jayesh.
