Select the most appropriate option that can substitute the highlighted segment in the given sentence.
Sivamani is working as an electrician for the past 22 years.

Correct option is B

The correct substitution of the highlighted segment is ‘has been working’ to make the sentence grammatically and contextually correct.
Explanation:
· The sentence refers to an action (working as an electrician) that started in the past and continues in the present. For such cases, the present perfect continuous tense is used.
· Correct sentence: Sivamani has been working as an electrician for the past 22 years.
Grammatical Rule Used:
· Present perfect continuous tense: Subject + has/have been + verb (-ing) + time frame.
Why Other Options Are Incorrect:
· (a) had been worked: Incorrect, as "had been" is used for past perfect, and "worked" is the passive form.
· (c) have been working: Incorrect, as the subject Sivamani is singular and requires has instead of have.
· (d) would work: Incorrect, as it implies a hypothetical or future action, which is not the case here.
