d. leaders of other religions

As popes tried to increase their power, aside from bishops they also came into conflict with kings. Option A is correct.

Papal supremacy is understood as the doctrine of the Roman Catholic Church that the Pope, due to his office as Vicar of Christ and as the visible foundation and source of unity, and as pastor of the whole Christian Church, possesses full, supreme, as well as universal power over the whole Church, a power which he can always exercise unhindered."The Pope enjoys, by divine institution, supreme, full, immediate, and universal power in the care of souls."

the iconic cartoon that you are talking about is probably a man standing on top of a country with his legs spread wide. 

this cartoon suggests that europeans are powerful enough to subdue an entire continent. this was a satirical image that was drawn during the time of the colonization of the british empire in africa.

this image was inspired by the plans of the british empire to create telegraph lines all over africa promoting the further spread of its colonies through faster communication. the picture depicts the colonial mentality of the british empire in general as well as the struggle of africans to claim their own land. hope this ! (:

i actually think that the correct answer is: the roman senate power's could not exercise complete control over the common people or plebeians.

.hope that . and can i get brainest point
