To determine through which gas sound waves travel the fastest, we need to compare the speeds of sound in each of the gases listed in the table. The provided speeds of sound in the various gases are:

- Air (dry): 346 m/s
- Ammonia: 415 m/s
- Methane: 450 m/s
- Nitrous oxide: 263 m/s

We need to find the gas with the highest speed of sound. Let's examine each:

1. Air (dry): 346 m/s
2. Ammonia: 415 m/s
3. Methane: 450 m/s
4. Nitrous oxide: 263 m/s

From this list, we can observe that methane has the highest speed of sound at 450 m/s.

Now, let’s match this finding to the provided choices:

A. Nitrous oxide
B. Ammonia
C. Air
D. Methane

The correct choice is D. Methane.

Therefore, the gas through which sound waves travel the fastest is Methane.
