Max Function Question

For purposes of evaluation let us assume the following: There is one table called Table1 with three columns a, b, c populated with the following data

a b c
- - -

1 1 1
1 2 3
2 2 2
2 3 5

My desired resultant record set would be a b c
- - -

1 2 3
2 3 5

The following function is close to what I need but not quite it.   Select a, mac(b) from Table1 group by a;

There is a third column c whose value I wish to include.   Select a, c, max(b) from Table1 group by a; Will not work since there is not aggregate function for column c.

Also the following is close but still lacking   Select a, b, c from Table1 where
    a in (select a from Table1 group by a) and     b in (select max(b) from Table1 group by a); Returns:
a b c
- - -

1 2 3
2 2 2 <--Not desired
2 3 5

Hope I have made my needs clear and am thankful for all help
