The correct answer is 'b', sound signals.
Explicación
## Step 1The problem is asking us to identify the type of signals that guide vessel operators safely along waterways. The options provided are: prolonged signals, sound signals, and traffic signals.## Step 2We need to consider the context of the problem. The problem is about waterways, which are bodies of water where vessels operate. Therefore, the signals that guide these vessels would be those that can be heard, not seen.## Step 3Considering the context, we can eliminate 'traffic signals' as they are typically used on roads, not waterways. They are not audible and therefore cannot guide vessels.## Step 4Between 'prolonged signals' and 'ound signals', the latter is more appropriate. 'Prolonged signals' could refer to any type of signal, not necessarily those that can be heard. 'Sound signals', on the other hand, are specifically designed to be heard and can guide vessels.
