• B. one species is harmed and other is unaffected
• C. one species is benefited and other is unaffected
• D. booth the species are harmed

Answer 1

The correct option is B one species is harmed and other is unaffected

When one species is harmed and the other is benefited, it is called parasitism. Mutualism is the case when both the species is benefited. Commensalism is the condition in which one species is benefited and another is unaffected.

So, option B is the correct answer.
