To find the rank of child C, we need to add up the number of successful tosses for both sets of ten tosses:

For the first set: 
3 + 4 + 5 + 3 + 5 + 4 = 24

For the second set: 
2 + 2 + 2 + 0 + 6 + 2 = 14

Now we can rank the students based on their total number of successful tosses.

1. E: 24 
2. A: 23 
3. B: 22 
4. F: 19 
5. C: 17 
6. D: 8

Since we are looking for the rank of child C, the answer is 5. However, since the options are unsigned ranks, we don't need to worry about ties, so the answer is 3.5 since C is in the middle of a group of three students with 17 successful tosses each.
