Identify the error in the given sentence.

My colleague always works latest than me.

The correct option containing the error is "latest".

Step-by-step Explanation:

1. Analyze the sentence structure:
The given sentence is: "My colleague always works latest than me."
Here, two entities are being compared: "My colleague" and "me" (in terms of how late they work).

2. Identify the type of comparison:
The word "than" is a conjunction used to introduce the second element in a comparison. When comparing two things or people, we must use the comparative degree of the adjective or adverb.

3. Examine the adverb used:
The word "latest" is the superlative degree of the adverb/adjective "late" (late ⇒ later ⇒ latest).
Superlative degrees are used when comparing three or more entities (e.g., "He works the latest of all"). For a comparison between two parties, the comparative degree "later" must be used instead of the superlative "latest".

4. Correction:
Replacing "latest" with "later" makes the sentence grammatically correct: "My colleague always works later than me."
