15 i'm stuck on this : ( asap!

an author claims that "zoos do more good than harm." the author provides the following as support for the claim:

in 2012, the well-respected research firm martin and associates conducted a study on the request of animal rights activists. the published report was overwhelmingly one-sided. head researcher adeline moreno summed up the results by stating, "the importance of zoos cannot be overstated. the economic and educational benefits for humans are great. the protection and preservation of endangered species is even greater."

which choice best describes the support the author provides?

it is effective support for the claim.
it is ineffective support because it does not prove the claim.
it is ineffective support because it presents opinion rather than fact.
it is ineffective support because it provides no source for the information.

i feel like it's a, but i'm not totally sure.
