Explanation:

Step1: Identify energy levels

The ground - state is \(n = 1\) and the third excited state is \(n=4\).

Step2: Look for the transition

An emission is a transition from a higher to a lower energy level. We need to find the arrow that goes from \(n = 4\) to \(n = 1\).

Step3: Match the transition

From the diagram, transition C goes from \(n = 4\) to \(n = 1\).

Answer:

C
