Definitely A.

One thing I remember from my early days of engineering schooling is that I must look at *all* of the possibilities -- even if some of the ideas are not fully developed or even slightly non-sensical.

Often new and better solutions are derived by sleeping on these crazy ideas -- sometimes the ideas contain hidden merits that may cause you/others to see the problem in a different light. That is why discussion is so effective.

What's important is the end result. Did a fellow monk ultimately get the answer the were looking for?

BTW, I highly value your opinion, because you always seem to be spot on.
