  Underleading an Ace against a suit contract is the absolute worst opening lead in Bridge.
A careful look at this hand shows just how bad it can turn out.

And leading from a doubleton in a suit the opponents have bid is almost as bad.

So by process of elimination you lead a trump, probably the 9.

And when South plays ♣s, (preparing to ruff in dummy), you will win and play another trump.
Even if South guesses the ♠s correctly he will not be able to make the contract.
