Conditional Formatting code help

I have 300o rows that I need code in, is there a faster way to write this so I don't have to write a policy rule for each row?

What I need to accomplish: If "Dismissed" is selected in Column C I need it to turn Cells A,B, & C in that row Yellow but only that row. Above is the only way I can think to do it but then I would have to basically copy and change the row # from Cell 3 to 3003 and boy I'd really like to avoid having to spend the time doing that. I'm sure there is a way to do this in a much simpler faster way, I just can't think of how to get it done other than the way I don't want to do it.
