It is in the man pages however it may be a bit confusing.

The best RRA will be chosen automatically, now you only need to know
what defines "best" :)

In stead of trying to explain it, I'll be lazy and assume you know C.
Please look at the source, file rrd_fetch.c, function rrd_fetch_fn

Feel free to ask again if you don't know any C.  I'll try and explain.
Before you do so however, try playing with "rrdtool fetch" a bit,
in particular try changing the end time to be on an exact multiple of
stepsize times steps.
