Answer 1

B. Before he proposed his heliocentric theory most Europeans believed that the sun revolved around the Earth.

Answer 2

The correct answer is B. Most notable about Nicolaus Copernicus' work was that before he proposed his heliocentric theory most Europeans believed that the sun revolved around the Earth.

In the 16th century, Nicolaus Copernicus published a model of the Universe in which the Sun (and not the Earth) was in the center. The previous hypotheses were maintained since the 2nd century, when Ptolemy had proposed a geocentric model that was used by astronomers and religious thinkers for many centuries.

Copernicus' theory established that the Earth turned on itself once a day, and that once a year it made a complete revolution around the Sun.
