what is an effect of la niña?\na. fish populations off the coast of peru decrease.\nb. florida\nc. alaskan…

Brief Explanations:

La Niña is associated with stronger than normal trade - winds. This leads to upwelling off the coast of Peru, which is beneficial for fish populations there. It also often causes South America to be wetter than normal and has no direct link to Alaskan fish populations. Florida is not a typical direct impact in terms of the main effects of La Niña.

Answer:

None of the options are completely correct as stated. But if we consider the closest correct - related idea, during La Niña, the upwelling off the coast of Peru is enhanced, which is good for fish populations (opposite of option A), and South America generally gets wetter (opposite of option D). Since the options are not ideal, if we assume a mis - statement in option A and consider the normal situation of upwelling benefits for fish off Peru, we could say that none of these options accurately represent the main effects of La Niña. If we had to choose the least wrong, we note that La Niña is not associated with the fish population decrease off Peru as stated in option A, and not with the changes in Alaska or the drying of South America as in options C and D. So, if forced to choose, we might say the question has incorrect options.
