C Correct answer
Explanation

Arrange the 5 apples and 5 cherries first (10 items total). The number of ways to arrange these is 10! / (5! * 5!) = 252. There are 11 possible slots for the 10 identical oranges. We must choose 10 slots out of 11, which is C(11, 10) = 11. Total ways = 252 * 11 = 2772.
