Since the problem says "...all numbers k, l and m...", I have considered the case that all of them have zero value (k=l=m=0)?

In such case, the answer would be E instead of D, because 0 makes both parts of the equation to be equal, and other integers don't.

What do you think? The question doesn't say "all unequal numbers distinct from 0 k, l, m"...

Thanks,
