Step-by-step explanation:
The question asks which changes Reform Jews and the Protestant Reformation have in common. The correct answer is c. Desire for reform and adaptation. Both movements emerged from a desire to update and modify their religious practices to be more in line with contemporary values and thoughts. Reform Judaism arose in the 19th century and sought to modernize Jewish traditions, making them more applicable to the lives of Jews at that time.
