Final answer:
Destructive interference of waves from Sea A and Sea B results in a wave height of 3 meters, which is the difference between the two original wave heights.
Step-by-step explanation:
When considering the interference of waves from two separate areas, such as Sea A and Sea B, destructive interference occurs when the crests of one wave align with the troughs of another wave, effectively reducing the resultant wave height. Given that Sea A has wave heights of 2 meters and Sea B has wave heights of 5 meters, the height of the waves resulting from destructive interference would be 3 meters, which is the difference between the heights of the two waves (5 meters - 2 meters). This outcome corresponds to answer choice c) 3 meters.
