SQL Problem

I am facing problem in getting the desired result.

Here is my problem..
my table look like
----->temp(A,B,C);

Data is as follows:
A B C
-- -- --

A1 B1 C1
A1 B1 C1
A1 B1 C1
A1 B1 C2
A2 B2 C1
A2 B2 C1
A2 B2 C2

For same A,B I need the rows with maximum of same C. & also want to know which C.

I am able to find
A1 B1 3
A2 B2 3
using this query.
select A, B , MAX(Count_C ) as MAXC from (
SELECT Testtable.A, Testtable.B, Count(Testtable.C) AS Count_C FROM Testtable
GROUP BY Testtable.A, Testtable.B , Testtable.C ) GROUP BY A, B But I am mainly interested in what is the corresponding value of C for both rows.
So what I need as result is:
A1 B1 C1
A2 B2 C1

Thanks in advance
