Answer:
b). Luca is liberal; Fabian is conservative.
Step-by-step explanation:
As per the given situation, the second statement is most adequately true that 'Luca is liberal while Fabian is conservative.' The descriptions regarding Luca being open to political, as well as, social changes reflects that he is a broad-minded individual as reflected by his statement 'what about people who are not well-informed?' while Fabian's attempt to stick to traditional beliefs and averse to change his outlook towards society displays his unprogressive thought. Thus, these details show that Luca possesses a liberal perspective while Fabian seems highly orthodox. Thus, option b is the correct answer.
