Predation Is not likely to be a limiting factor on a dolphin population. 
A) Predation 
B) competition
C) Drought
D) Disease 

I see that it's correct. Dolphins have been dealing with predators for millions of years. They've only been becoming extinct because of us humans from things like pollution. Their natural predators aren't affecting them too much.

Have a nice day! :)

Where are the options?
