Answer:
The correct answer is - commensalism.
Explanation:
The mutualistic relationship between two organisms where one of them is benefited and the other organism neither benefited nor harmed is a commensalism relationship.
In the given example, The shrimps are benefited as they have to use very little or no energy whereas the sea cucumber is unaware of this so neither benefited nor harmed.
Thus, the correct answer is - commensalism.
