Final answer:
Pietro da Cortona's painting for the Barberini family would likely reflect passionate support for the current pope, who was a member of the Barberini family. Therefore, the correct option is B.
Step-by-step explanation:
The painting by Pietro da Cortona could be considered emblematic of the Baroque era's interest in drama, emotion, and the intertwining of the arts with the politics of the time. The Barberini family, for whom the painting was made, was closely connected with Pope Urban VIII, a member of the Barberini family. The artwork portraying support for the current pope would have likely reflected passionate support, as the Barberini family would probably desire to emphasize the grandeur and legitimacy of their family member's papacy through art, a common practice during this period.
