Which statement correctly matches the TMJ development stage to its time?

Explanation:
The TMJ develops in a sequence where the earliest stage is a mesenchymal condensation called a blastema, which forms around 7–8 weeks. This blastema is the primitive joint structure from which the condyle, articular disc, and capsule will arise. Cavitation—the creation of the joint space—occurs after this initial stage, and maturation of the joint tissues follows later as they differentiate and become functionally organized. So pairing blastemic at 7–8 weeks matches the initial formation of the TMJ, while the other options place later stages or different timings in the wrong order.
