Question

in what way did the new japanese constitution change the role of the emperor?
he gained the power to choose the prime minister
he was forced to declare he did not have divine power
he was no longer the ceremonial head of state
he became a permanent member of the diet.

Explanation:

The post-WWII Japanese Constitution (1947) redefined the emperor's role. It stripped the emperor of divine status via the Emperor's Declaration of Humanity, making them a symbolic, ceremonial head of state. The other options are incorrect: the prime minister is chosen by the Diet, the emperor remained a ceremonial head (this was the new role, not an end to it), and the emperor is not part of the Diet.

Answer:

He was forced to declare he did not have divine power
