Each of the given conditions is necessary for a self-sustained controlled fusion reaction to operate. Confined for sufficient time period ensures that the reaction has time to build up and sustain itself, high density ensures that there are enough fuel particles close enough to each other to interact and undergo fusion, and sufficiently high temperature ensures that the particles have enough energy to overcome their mutual repulsion and fuse together. Therefore, all three conditions - confined for sufficient time period, sufficiently high density, and sufficiently high temperature - must be met for a self-sustained controlled fusion reaction to occur.
