If there are 3 vertical, and 3 horizontal, circles to be filled in using a set of given numbers only once, you would need 9 numbers.
For instance,
8..1..6
3..5..7
4..9..2
Can you clarify your problem statement of "...using each of the numbers once and only once...".
No, I am not sure.
The exact diagram looks like this

The circles are to be filled in with the numbers given.
The possible multiple choice answers given are:
A) 7, 8, and 9 B) 7, 9, and 11
C) 9, 10, and 11 D) 8, 9, and 10
I think I see what you are driving at now.
9.8.10

10 and the same variations as shown above.
11.7.10

9 and the variations.
I still don't understand?
Also the two verticle circles are actually under the second horizontal circle, not the first. For some reason it didn't post like that.
(I don't know if that makes a difference or not)
What I don't think I understand are the purpose of the circles, or maybe it is the purpose of the placement of the numbers (which is really the same thing)
I am sorry I am not grasping this.
The circles are just there to show us where they want the numbers. 3 across and 3 down in the middle. Both numbers across and down the middle must equal the same number.
