Choose the sentence that demonstrates correct parallel structure with correlative conjunctions.

Answer and explanation

Correct answer: A. The program will either reduce operating expenses or increase revenue.

  1. Step 1: Correlative conjunctions ('either... or') must join grammatically parallel elements.
  2. Step 2: In the sentence 'The program will either reduce operating expenses or increase revenue.', 'either' is followed by verb phrase 'reduce operating expenses', and 'or' is followed by parallel verb phrase 'increase revenue'.
Answer
The program will either reduce operating expenses or increase revenue.
Why not the others: The sentence ending 'or increasing revenue' pairs base verb with gerund ('increasing'); the sentence 'The program either will reduce...' places 'either' before auxiliary 'will'; the sentence 'reduce either operating expenses or to increase revenue' pairs noun phrase with infinitive.
