Select the most appropriate Option to fill in blank number 3.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. was.
The sentence is: "Check-up (3)___________ set up in the west of England and after two years moved to London..."
Since the company Check-up is singular and the action happened in the past, the correct verb form is "was".
Option 1: is is present tense and incorrect because the sentence refers to a past event.
Option 3: are is plural and incorrect because Check-up is singular.
Option 4: has is present perfect auxiliary but incomplete on its own here.
