Correct option is A
The correct substitution is (a) have borne.
Explanation: The subject “ efforts” is plural, so the helping verb must be have, not has. Also, the verb “borne” (past participle of bear, meaning “to produce”) fits here correctly.
Grammatical Rule Used:
· Subject-Verb Agreement: Plural subjects take plural verbs.
· Perfect tense uses have/has + past participle.
Correct Sentence:
The efforts of the Government... have borne fruits.
Example:
Our hard work has borne results. (correct)
