'a' builds thickness in sente against the white group. 'b' presses White low on the right. 'c' might build shape afterwards, somewhat loosely connecting 'a' and 'b'.
'd', 'e', or 'f' could take the second move in that corner, but I can't say what's best. Maybe this calls for probing something else first, but I'd be reluctant to take gote with something like 'c' instead of playing in this big area.
Playing in the lower left with 'g', 'h', or 'i' is also big, but again, I can't say what's best.
Finally, 'j' is almost sente, which either means that Black could build something on the wide left side, or that the left side is not as wide as it looks.
I think that I would play 'a' in any case. White then probably wouldn't answer 'b' and take the lower right, after which it feels slow to me to follow up on 'b' (White would go on with the press or a counter pincer in the lower left side), so I guess 'b' is too early at that point.
I'd be very much inclined to play the lower right now, but it also feels big to play on the left side first, so White will probably then ignore almost anything there and play in the left. On the other hand, if Black plays in the lower left, White's best move in the right seems to be the “classic” tight shimari, which we nowadays regard as a bit slow (with the possibility of the shoulder hit and all that).
So finally, I'd feel like playing 'g' now. It seems like taking a stance (in Karate, I'd call it “kamae”; is that the right word here, too, John?).
My prediction (wishful reading?) then goes something like this:
