Solution
The correct option is B Commensalism
Mutualism is a mutually beneficial relationship between individuals of two different species. None of the two is capable of living separately. For example, nitrogen-fixing Rhizobium bacteria living in root nodules of leguminous plants.
Commensalism is an interaction in which one organism is benefited and the other is neither benefited nor harmed. For example, Barnacles are often attached to the surface of whales for shelter and obtaining more food.
In amensalism without deriving many benefits, one organism inhibits the other by secreting allochemics. The phenomenon is called antibiosis. For example, Trichoderma checks the growth of Aspergillus.
In parasitism, one organism called as parasite obtains nourishment and shelter from another organism called as host. e.g., Plasmodium, Trypanosoma.
In predation, one organism called predator captures kills and eats another organism called prey. Predators are generally carnivorous but some herbivorous animals which destroy whole plants or seeds are also called as predators. e.g., Big cats like lion, tiger etc, birds feeding on seeds of plants.
Therefore, the correct answer is 'Commensalism'.
