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!!!

Is this sentence grammatically right? Let us see.
What is slowing metabolism and reproductive activity? Is it weather alone or lake toxicity as well? If you want to mean that both are responsible, then you have to necessarily put a comma after 'weather', so that the present participle ‘slowing’ modifies the entire noun idea before it. Otherwise, ‘slowing’ will be simply modifying weather alone and hence structurally and stylistically and semantically wrong. You can’t skip the comma before ‘slowing’

'.. slowing the growth' seems to refer to the researchers
e.g. Researchers blamed poor health conditions on poor dietary habits, concluding that better diet would help save lives. --> Here, Researchers conclude => 'concluding ...' refers to researchers.
Dan identified the problem, using the latest technology --> again comma+verbing tells how Dan identified the problem; 'using ...' doesn't refer to problem here
Do you mean that the sentence (in question) structure like this:
I saw dogs dancing on the road --> here, "dancing on the road" refers to dogs
I saw cats and dogs dancing on the road --> "dancing on the road" still refers to dogs only. so, essentially, the sentence would mean i saw cats and dancing dogs.
So, to make the sentence mean dancing cats and dancing dogs, we'd have t introduce comma, and it'll look something like this:
I saw cats and dogs, dancing on the road. Does 'dancing on the road' refer to cats and dogs both? Isn't "dancing .." ambiguous since it could refer to "I" (that is i was cats and dogs while i was dancing) or "cats and dogs" (that is I saw dancing cats and dancing dogs)?

Please clarify the confusion: in one, ', verb+ing ...' modifies the subject and in the other, the object. thanks in advance.
