Final answer:
The theory that aligns with the idea that reality is multiple and subjective is Constructivism (option B). It posits that reality is constructed by human cognition and there is no single objective truth, with each group potentially having its own valid reality.
Step-by-step explanation:
The question that asks if reality is multiple and subjective can be answered through the perspective of different philosophical viewpoints. The correct answer to this question is option B) Constructivism, as this is the theory most aligned with the idea that reality is what humans cognitively construct it to be. Constructivism suggests that there is no absolute or objective truth and that realities are social constructs that differ among groups. According to constructivism, there can be many truths at once, with this plurality being the result of the multitude of perspectives and social constructions. In constructivism, the self-refuting basic claims of an objective or an absolute reality do not stand, as all knowledge and understanding of reality is subjective, based on individual or group constructs, and is influenced by language, power relations, and societal norms. Pragmatism, another theory presented in the options, argues that talk about reality serves social functions and doesn't necessarily reflect an external truth. However, it does not encapsulate the idea that reality is multiple and subjective as directly as Constructivism does.
