One of the women who … in the premises … been ordered to quit?

Analyze the question: This tests subject-verb agreement, especially with the structure "One of the + plural noun + relative clause."

Explain the concept:

• The main subject of the sentence is "One", which is singular. So the main verb ("been ordered") takes has.
• The relative clause "who ...... in the premises" describes "the women" (plural). The relative pronoun who refers to "women", so its verb must be plural: sell.

Step-by-step solution:

1. "who ___ in the premises": who refers to "women" → plural → sell
2. "One of the women ... ___ been ordered": the subject is "One" → singular → has

Full sentence: One of the women who sell in the premises has been ordered to quit.

Checking the options:

• A. sells / have: both wrong
• B. sell / has: both correct ✔
• C. sell / have: "have" is wrong
• D. sells / has: "sells" is wrong

Tip: In "One of the + plural noun + who/that + verb," the verb right after who/that is plural (it agrees with the plural noun), while the main verb of the sentence is singular (it agrees with "one"). Example: One of the boys who play here is my cousin.
