To determine which wave has the greatest amount of energy, we generally consider the relationship between energy and frequency for electromagnetic waves. The energy of a wave is directly proportional to its frequency; this means that waves with higher frequencies carry more energy.
If you have two waves, A and B, and you know their frequencies, the wave with the higher frequency will have greater energy. Without specific information about the frequencies or types of the waves, we cannot conclude which one has more energy.
Based on your options, if you don't have enough information about the frequencies or other characteristics of waves A and B, then the correct response would be:
There is not enough information.
