Final Answer:
The synonym for "truism" is Axiom so correct option is B.A truism is a self-evident and universally accepted truth. Similarly, an axiom is a statement that is widely recognized as inherently true.
Step-by-step explanation:
A truism is a statement that is undeniably true, often to the point of being self-evident or universally accepted without the need for justification. It expresses a truth that is so obvious and commonplace that it may seem almost trivial. For example, the statement "water is wet" is a truism because it articulates a universally acknowledged fact. On the other hand, an axiom is a self-evident and foundational principle that serves as a basis for reasoning or argumentation. Axioms are assumed to be true without requiring proof within a particular system or context. While both truisms and axioms convey notions of inherent truth, the former tends to highlight widely accepted truths in general discourse, while the latter is more commonly associated with foundational principles in specific fields, such as mathematics or philosophy. So the correct option is B.
