Hi Chris,
This is a hard problem and the solution is complex. Although I don't have much
argument with your analysis, the answer given on the website is different. I
came up with the same answer as you, but I think the reasoning against that
answer is something like the following.
If Black plays:
1... c3 forking the Rook and Pawn White plays,
2. bxc3 and Black has two choices:
2... Rxa3 or 2... Rxc3
If Black takes the A-Pawn, White advances the C-Pawn and now has a passed Pawn
that Black must deal with as well as guard the A-Pawn. So if Black tries to
get under the C-Pawn, White swings the Rook over to a2 attacking the A-Pawn.
And I don't think Black can defend both Pawns as well as take the C-Pawn.
On the other hand, if Black takes the C-Pawn, White swings the Rook over to a2
protecting the A-Pawn. Now if Black advances the D-Pawn to d2 the King moves
to e2 and the Pawn is attacked twice. Black now has to guard the Pawn while
trying to maintain pressure on the White Pawn at a3.
Maybe someone else has a better analysis for this problem. I will post the
given answer Monday.

Okay, lets try this again, smiles.
Now I have the board set up like it is suppose to be.
I think the best move is:
1. ... c3
With this move, you are guaranteed at least one pawn to promote, and possibly
more depending on whites respondence moves.
If white respons with:
2. bxc3 Rxc3
3. Rd1 Rxa3
Now you have two pawns open to possibily be promoted.
Or
2. bxc3 Rxc3
3. Ra2 Rd2
Or white might:
2. Rxd3 cxb2
If white takes your rook,
3. Rxb3 axb3, and you now have two pawns ready to promote. The game is
basically over for white.
Or
If white avoids the capture by,
2. Rxd3 cxb2
3. Rd1 or Rd4 ... Rxa2
Or he might even put your king in check by:
2. Rxd3 cxb2
3. Rd6# .. Ke7
No matter what you should be able to promote a pawn.
Sorry if the above is confusing, I have never written moves before having to
list out different possibilities.
