Identify the error in the given sentence.
My colleague always works latest than I do.

Correct option is B

Option (b) contains an error.
Error explanation:
· The word "latest" is incorrect because it refers to the most recent thing (e.g., "latest news").
· The correct word should be "later", which is the comparative form of "late."
Grammatical rule used:
· Later (comparative) is used when comparing two entities.
· Example: She arrived later than I did.
· Latest (superlative) refers to the most recent.
· Example: This is the latest version of the software.
Corrected sentence:
"My colleague always works later than I do."
