Most workers resigns to join new jobs within the same industry.

Correct option is A

The correct substitution of the highlighted word is (a) resigned.
Explanation:
· The verb resigns is incorrect here because the subject “Most workers” is plural, and the verb must agree with it in number.
· Additionally, the sentence talks about a general trend in the past, so past tense (resigned) is appropriate.
· Therefore, “Most workers resigned to join…” is the grammatically and contextually correct form.
Grammatical rule used:
· Subject-verb agreement: Plural subject → plural verb
· Verb tense consistency: Past events are described using the past tense.
Example:
❌ Most workers resigns after a few months.
✅ Most workers resigned after a few months.
