What type of relationship is observed between insect-pollinated flowers and their pollinators?

Refer to the given table that summarizes the interactions between two organisms (organism $1$ and organism $2$). Identify the types of interaction ($A, B$,and $C$) and select the correct answer.

Benefit	Mutualism,Predation,$B$
Harm	$A$,Competition,Amensalism
No Effect	Commensalism,$C$,$-$

$(i)$ $A$ can be either predation or parasitism.
$(ii)$ $B$ can be either commensalism or amensalism.
$(iii)$ $C$ can be amensalism.
$(iv)$ $A$ can be amensalism.
