how to filter the rows based on a column which contains duplicate values...

Hi,

I'm not sure you've been too clear in your request here. If column C contains single-letter entries such as A, B, C... then how is it possible to filter for entries, as you say, "equal to (A B C)"? (Is this a text entry consisting of A followed by space followed by B followed by space followed by C?)

Then perhaps you could explain in a little more detail?
