Final answer:

The conclusion that follows in a single step from the given premises is H ⊃ Q.

Step-by-step explanation:

The correct answer is Option B) H ⊃ Q 3, Simp.

To identify the conclusion that follows in a single step from the given premises, we need to apply the rules of logical inference.

  1. The first premise states that ∼N ∨ H.
  2. The second premise states that Q ⊃ ∼(∼N ∨ H).
  3. The third premise states that (∼N ⊃ Q) • (H ⊃ Q).

By applying the Simplification rule (Simp), we can deduce that H ⊃ Q is the conclusion that follows directly from the premises. Therefore, Option B is the correct answer.
