The red cheeked salamander is negatively affected, the imitator is positively affected.
H+ is positive and OH- is negative. When you put the charge with the name, it becomes quite clear. Only on certain occasions can hydrogen atoms become negatively charged but hydrogen usually loses electrons.
More likely to avoid extinction,
1-if we have a wide range of genetic variation, we are more likely to survive ( take a disease for an example if we all have the same genes for weak immunity then we all die, but if genetic variation exists its more likely that we survive)
2- larger population will mean more people, more people mean greater genetic variation due to sexual reproduction.
3-wide range of geographic choices decreases extinction because if an area is affected by a natural disaster the rest if the areas will survive
I believe it is A. Please forgive me if I am wrong.
