The following sentence has been divided into parts. One of them may contain a grammatical 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.
If the economy fails / this year it reflect badly / on the government.

The correct option containing the grammatical error is "this year it reflect badly".

Step-by-step Explanation:
1. Analyze the structure of the sentence: The given sentence is a conditional sentence: "If the economy fails this year, it reflect badly on the government." The conditional clause ("If the economy fails this year") is in the simple present tense, which typically sets up a first conditional sentence describing a likely future outcome.
2. Examine the subject-verb agreement: In the main clause, the subject is the singular pronoun "it". The verb paired with it is "reflect" (base form). grammatically, a singular third-person subject ("it") requires a singular verb ("reflects"). Using the plural/base form "reflect" with a singular subject is incorrect.
3. Apply conditional rules: In a first conditional sentence structure, the main clause typically uses the future tense:
If + simple present (condition), will + base verb (result).
Therefore, the phrase should be corrected to "it will reflect badly" (or "it reflects badly" if expressing a general fact).
4. Conclusion: Because the verb "reflect" does not agree with the singular subject "it" and fails to form the correct tense, the segment "this year it reflect badly" contains the grammatical error.
