Answer:
No, it is not rex. The answer should be C. partricians.
Step-by-step explanation:
Res publica is a Latin phrase, loosely meaning 'public affair'. It is the root of the word 'republic', and the word 'commonwealth' has traditionally been used as a synonym for it; however translations vary widely according to the context. Res' is a nominative singular Latin noun for a substantive or concrete thing—as opposed to 'spes', which means something unreal or ethereal—and 'publica' is an attributive adjective meaning 'of or pertaining to the public, people'. Hence a literal translation is, 'the public thing, affair'.
But really, I would really 100% go with D patricains. Go with D. D is the right choice! Hope this helps you!
