If no alteration was mentioned, than it shouldn't be raised.
In addition, that tritone leap between the Bb and the E♮ in the soprano is not really ideal and should be avoided (usually melodic tritones are avoided in the soprano parts), and it is better to start a melodic minor melodic line with the 5th degree instead of directly with the raised 6th. It is also better to avoid using the leading tone in the soprano (since in sometimes it might force you to solve it into a no 5th tonic). All are just suggestions.
I think the best solution for this issue would probably be taking the soprano to Eb and then to D, while the C (Alto) would go down to A and the G (Tenor) to F#. It would force you to get some of the voices a little low, but it is a proper solution for this situation, and it is very common to make a leap after a 4/2 chord.
You could fix it with replacing the Bb in the soprano before, but it would require you some more changes.
