The four distinct single digit prime possible are 2,3,5,7
Hence, the scepter is mounted with diamonds, rubies, emeralds, and sapphires in the ratio 2:3:5:7
So we could have 2x+3x+5x+7x or 17x gems.
If x=5, Option C(17*5 = 85) is the number of gems on the imperial scepter.

There are only 4 single digit-prime numbers. The ratio must be 2x : 3x : 5x: 7x.
Total = 17x
The answer must be a multiple of 17.
Answer C, 85 = 17 * 5
Answer C
