read the following paragraph:
the ocean is an important source of human food. according to the national marine fisheries service, more than twenty percent of the global population gets the majority of its protein from seafood. but ocean pollution threatens to cripple this vital resource. nowhere is this clearer than the fishing ports of southern vietnam, where industrial runoff has filled local waters with toxins. area fisherman say the few fish they can still catch look and smell too strange for buyers, and they can no longer make a living fishing.
what type of evidence is used to support the claim that \ocean pollution threatens to cripple this vital resource\?
anecdotal evidence
facts and statistics
expert opinion
no evidence

Explanation:

To determine the type of evidence, we analyze the support for the claim. The text provides the experience of "An Giang fishermen" (local fishermen in southern Vietnam) about how ocean pollution has affected their ability to catch fish that buyers will accept and their livelihood. Anecdotal evidence is based on personal accounts or stories. "Facts and statistics" would involve numerical data or proven facts (the earlier statistic about protein from seafood is separate, but the support for the pollution claim isn't statistical). "Expert opinion" would be from a professional's analysis, not a fisherman's personal story. So the evidence is anecdotal.

Answer:

A. anecdotal evidence
