B) They reinforced the idea that science alone provides all knowledge.

C) They challenged the certainty of Newtonian physics as an objective truth.

D) They provided a scientific basis for Freudian psychology.

Correct Answer: C

According to the text, developments like quantum mechanics and Einstein's theory of relativity 'undermined the primacy of Newtonian physics as an objective description of nature,' thereby challenging the long-held certainties of classical physics.

Freudian psychology introduced a new perspective on human nature by emphasizing the importance of...

A) rational thought in overcoming societal problems.
