Improve the highlighted part of the sentence. Choose ‘No improvement’ as an answer if the sentence is grammatically correct.
The sun was shining through the window.

Correct option is B

The correct substitution of the highlighted words is (b) No improvement.
Explanation: The subject “sun” is singular, and the verb “was shining” is in past continuous tense which is correctly used to indicate an action continuing in the past.
Grammatical rule used: Singular subject + was + verb (ing) = Past Continuous
Example: The rain was falling all night.
Information Booster: Always match the subject in number (singular/plural) with the correct auxiliary verb in continuous tenses.
Meanings of the other options:
· (a) were shined – incorrect passive form + wrong auxiliary verb
· (c) were shining – incorrect as “were” doesn’t match singular subject
· (d) was shines – incorrect; base verb after “was” is grammatically wrong
