Question

Which verb correctly completes this sentence?

Answer 1

I think it's number 3. Conoce

Answer 2

Conoce (3)

she recognizes your parents' home

conocen is plural and monica is only one person so that is false
saben is (they know) again plural and referring to someone other than monica
and sabe is "know" but translated over it does not make sense because it has a different meaning
