Parts of the following sentence have been given as options. One of them may contain an error. Select the part that contains the error from the given options. If you don’t find any error, mark ‘No error’ as your answer.
The thing about anger is that it can either been a helpful emotion or a discouraging one.

Correct option is D

Option (d) contains an error.
The verb "been" is incorrect in this sentence because it requires a helping verb such as "has" or "had" to be grammatically correct.
Instead, the correct form should be "be" (as "can" is a modal verb and should be followed by the base form of the verb).
Corrected sentence:
The thing about anger is that it can either be a helpful emotion or a discouraging one.
Grammatical rule used:
· Modal verbs (can, could, shall, should, etc.) must always be followed by the base form of the verb, not past participles like "been."
Example:
· Incorrect: He can been late sometimes.
· Correct: He can be late sometimes.
