I can do my best to explain my reasoning:

"are" implies a state of being of the horns. the horns are trimmed = currently the horns are being described as trimmed.

"have been" is referring to a past action. they're wondering if visitors will come after the action has been carried out

I'm not even sure this is correct as I haven't studied grammar in years, but that's how I read it.

I read "have been" the same way - action completed before another action. It both actions are in the past you would probably see "had been" Toursits stopped coming because the animals' horns had been...

I got C without really looking at verbs though because I always have trouble picking the correct vb: the tourists can either come or not, two options so it has to be "whether" which leaves A, B, C

A - The "and" changes the meaning and makes it seem as if there is a two part question "will tourists come, and will tourists come to see the animals" Also not clear whether the animals' or the tourists' horns are trimmed
B - their doesn't have a clear antecendent
C - correct

C. i choose it for its clearity as "animals" refers to rhinos where as "they" is ambigious.

C. whether is right, so we have to decide among A,B,C. A writes "will continue to.... and see..." so is wrong..it needs to be " to...to". B is wrong because says one once....??
