I'm still unsure how answer C strengthens this argument. It seems that the premises present a correlation and the conclusion is causal, so we want to strengthen that causal explanation by eliminating all other explanations besides the mild winter. But the fact that predators are more likely to prey on birds when they are visiting feeders just gives an alternate cause for the birds' foraging. Doesn't that end up weakening the conclusion? (I'll re-read the argument because I might be misrepresenting it but that was my thought process when solving this question).
