Under Stalin all of the following were true, EXCEPT A. non-Russian minorities were often persecuted
В. questionable literature, music, and art was banned
C the role of religion increased and became more prominent
D nationalist uprisings of other groups were suppressed

C the role of religion increased and became more prominent

Explanation:

During Stalin's regime, religion was banned and it was practically removed from the country. Only during world war 2 did Stalin let religion back in and only to raise morale for the troops and civilians. But he was very bad to minorities just like he was to the Russians, he ordered many artists to be jailed or killed and nationalists of any sort were not only suppressed but punished severely.
