The average of 5 quantities is 6.

Therefore, the sum of the 5 quantities is 5 * 6 = 30.

The average of three of these 5 quantities is 8.

Therefore, the sum of these three quantities = 3 * 8 = 24

The sum of the remaining two quantities = (Sum of all 5 - Sum of 3 quantities) = 30 - 24 = 6.

Average of these two quantities = 6/2 = 3

Choice C is the correct answer.
