Help with sorting unique data in two different columns

Hi All,
I am trying to filter about 1000 lines of data and I am having no luck. I have used the advanced filter to determine unique entries of one column but my request is a bit more specific than that.

I have two columns of data. In Column A I have numerous different numbers and many are repeated. In column B I have numerous other numbers and some are repeated. In column C I have data that is relevant and most travel with the data but is not a sort criteria.

What I am trying to do is sort the lines by unique data in columns A and B.

I have attached the data

What I want to do is filter the combination so its only listed once.. For example

Column A Column B Column C
A A Some Description
A A Some Description
A B Some Description
B C Some Description
B C Some Description
B C Some Description
C D Some Description
C E Some Description
C F Some Description

I would like the data to spit out something like below

Column A Column B Column C
A A Some Description
A B Some Description
B C Some Description
C D Some Description
C E Some Description
C F Some Description

To be clear, even though I used letters for my example, in reality the items in column A will never be listed in Column B and vice-versa.

Thanks for any help!
