Options for the question have not been given. They are as follows:
Both organisms benefit in mutualism and parasitism, but only one benefits in commensalism.
Both organisms benefit in mutualism, only one benefits in parasitism, and none benefits in commensalism.
Both organisms benefit in mutualism and commensalism, but only one benefits in parasitism.
Both organisms benefit in mutualism, but only one in parasitism and commensalism.
Answer:
Both organisms benefit in mutualism, but only one in parasitism and commensalism.
Step-by-step explanation:
Mutualism is a type of interaction in which both the organisms are benefited. For example, fungi absorbs nutrients for algae, and in return algae synthesizes food material for fungi. This symbiotic relationship is called lichen.
In parasitism, one organism is benefited and other is harmed. For example, ticks and lice survive as parasites on higher organisms. They feed on the blood of the hosts and harm them.
In commensalism, one organisms is benefited and other is neither benefited nor harmed. For example, Remora fish attaches to sharks for protection and also feeds on the leftovers of the shark's hunt. Remora is benefited but the shark is not affected in any way by this relationship.
