SQL Server 2008: TOP 10 and distinct together

Question

As the title says, I\'m using SQL Server 2008. Apologies if this question is very basic. I\'ve only been using SQL for a few days. Right now I have the following query:

Answer 1

SELECT TOP 14 A, B, C
  FROM MyDatabase
  Where EXISTS 
   (
     Select Distinct[A] FROM MyDatabase
    )
