What worldview did most Europeans hold on to in the 16th century?

(a) Heliocentric

(b) Empirical

(c) Geocentric

(d) Fraternal

Worldview? Well, it depends on what you're asking. If you're asking the actual world, then it's the renaissance, in which case it's Empirical. Though if we're talking universal perspective, I'd think it would be A, Heliocentric. Go with A.
