Answer:
C. Ethos
Step-by-step explanation:
Ethos is the fundamental character of an individual or institution that distinguishes them from others.

They are not presented in a positive way and this means that Thomas Paine found them wanting in character.
The institution is hereby classified as a wildly unreasonable character. Paine was clearly against their dealings which was why he condemned them.
