Researchers blamed the low rate of growth in the harbor's toad population on lake toxicity as well as on the weather, hotter and more humid than average in the Ohio region, which slowed metabolism and reproductive activity.
which doesn't have a clear antecedent in choice A, actually which generally refers to the noun immediately preceding it...however here which is too far from its actual antecedent (weather) thus having an ambigous antecedent.
IMO B is the correct answer.

after which, a noun modifier is needed. Only , which is correct here. --> B

Which can only modify a noun,here "which" has to modify the clause "that the weather being hotter & more humid than average" is responsible for the slowing down

This is exactly what I needed to know for the question. If I had known this grammar rule I think I would have gotten the question right!

B..

relative pronoun which is used to modify the immediately preceding noun weather.
present participle- slowing is correctly used to describe the activity of weather.

can someone explain me why "slowing" is right? (answer B).

shouldnt it be blamed for slowing or something like that?

thanks.

Please have a look at MGMAT SC book Ed. 4 page 91 (chapter 6 on modifiers).
My take is on B because "which" must refer to the word just preceding the comma. Also 'ing' form is correctly used to display the result or an outcome of some happening!!!
