If acid drainage will reaches groundwater, it may persist for decades or centuries.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. If acid drainage will reaches.
The word "will" is incorrectly used in a conditional clause. In conditional sentences, the verb in the if-clause is always in the present simple tense, not the future tense.
The correct structure is- If + subject + present tense, subject + future tense.
The verb "reaches" is correct for the singular subject "acid drainage", but the presence of "will" makes it grammatically incorrect because "will" is not needed in the if-clause.
Hence, the correct sentence is- "If acid drainage reaches groundwater, it may persist for decades or centuries."
