Who picks the type of the Basic Attack?

Charm of Misplaced Wrath (Heroes of Fallen Lands, p206)

The target makes a basic attack against a creature of your choice as a free action. The basic attack gains a +2 power bonus to the damage roll.

This is a 1st level Wizard encounter power, if it matters.
Can I make the target do a Ranged Basic Attack (so it provokes attacks of opportunity) or does it get to pick the type of Basic Attack?
