Which key is the most appropriate for the marked measure?

ANSWER

The previous passage ended with the authentic cadence and the key was changed from marked measure as many accidentals are attached. The first chord in the marked measure is a dominant 7th and the second is a major triad which resolves the dominant chord. The second chord consisting of E, G# and B is the tonic of the new major key. Correct answer is 2.
