  Lead the 4.

This is a close call. The top of your ♠ honor sequence is very tempting, but even when you find partner with the ♠K you can still only establish three ♠ winners to go with your ♣A.
Unfortunately, that's not enough to defeat the contract.

Leading a from your 5-card suit is riskier, but it has the potential of setting up an additional winner. In this hand, as you see, the lead gets you 4 winners to go with your ♣A.
