Question

Which verb best completes this sentence?

Answer 1

A.See
Because will see is future tense , had seen is past and will have see is future present tense and see is present tense which is correct.

Answer 2

A. See

It's A because, "Right now I will see several porpoises swimming next to our boat." doesn't make any sense. Had seen and will have seen does not make sense, too. Hope this helped you! :)
