Parts of the following sentence have been given as options. One of them may contain an error. Select the part that contains the error.
Educators must roll up their sleeves and do a more best job of teaching critical thinking.

Correct option is C

Option (c) contains an error.
Explanation: The phrase "more best" is grammatically incorrect because “best” is already a superlative. Using “more” before it is redundant. The correct form should be “a better job” or simply “the best job”.
Grammatical rule used: Superlative adjectives (best, worst, tallest) should not be modified with “more” or “most” as they already represent the highest degree.
Example: Incorrect – She is more best at dancing.
Correct – She is the best at dancing.
