Neither of the proposed routes through the mountain pass ______ safe for commercial transport during the winter storm season.

Answer and explanation

Correct answer: A. is

  1. Step 1: Identify subject-verb agreement: 'Neither' is a singular indefinite pronoun when functioning as the grammatical subject.
  2. Step 2: It requires a singular verb: 'is'.
Answer
is.
Why not the others: 'are' and 'were' agree incorrectly with the plural noun 'routes' in the modifying prepositional phrase; 'being' is a non-finite participle.
