The Phillips screwdriver has this type of head.

Explanation:
Phillips screws use a cross-shaped recess that matches a cross-shaped driver tip. The four lobes of the tip grip the four wings of the screw head, which helps center the driver and spread the torque more evenly, reducing cam-out in typical use. The other shapes belong to different screw types: a slot is a single straight groove for a flat-blade screwdriver; hexagonal heads require an Allen key; triangular heads are a three-point profile used on some security or specialty screws. That cross-shaped profile is why the correct answer is cross-shaped.
