In the context of the question, ie where 'eliminate' is being used as a noun - A5 is your man.
In addition:
As Al points out the word is also used in bouldering to refer to the elimination (removal) of holds from a boulder problem. For example, you might attempt to complete a boulder problem without using a key foothold. If successful, you are said to have eliminated that foothold from the boulder problem
As Steve points out, the word is also used where aid moves (standing in slings and hammering pitons into the wall) have subsequently been free climbed. The aid is said to have been eliminated.
