Select the most appropriate option to substitute the underlined segment in the given sentence.
It is u̲s̲ ̲r̲e̲s̲p̲o̲n̲s̲i̲b̲l̲e̲ for the current situation of the company.

Correct option is D

The correct substitution of the highlighted words is (d) we who are responsible.
Explanation: The pronoun "we" is a subjective pronoun, and since it is the subject of the clause, "we" is appropriate, not "us" which is objective. The clause following it “who are responsible” further modifies “we”.
Grammatical rule used: Use subject pronouns (I, we, he, she, they) when they function as the subject of a sentence or clause.
Example: We who work hard deserve success.
�� Information Booster: Clauses beginning with "who" usually describe or identify the subject and thus must follow subject pronouns.
Other options explained:
· (a) we that responsible – grammatically incorrect; “that” doesn’t fit with the subject “we”
· (b) who are responsible – incomplete; lacks a subject before the clause
· (c) us that are responsible – “us” is an object pronoun; incorrect in subject position
