The Correct Option is C

Solution and Explanation

Step 1: Understanding the Ochi-Hubble Spectrum.
The Ochi-Hubble spectrum is formulated for conditions where there are two peaks in the energy distribution, particularly useful for modeling waves with multiple dominant frequencies. 
Step 2: Application to Sea States.
This spectrum is often used when there are more than one significant wave component in the sea, which can occur in conditions with a mixture of different swell and wind-sea waves. 
Step 3: Conclusion.
Therefore, the Ochi-Hubble spectrum is the correct answer for a two-peak wave energy spectrum. 
Correct Answer: (C) Ochi-Hubble spectrum.
