What is proposition? A proposition can be defined as a statement that expresses your position on a subject clearly and without any doubt.
There are three types namely:
proposition of fact
proposition of value
proposition of policy
The one that correctly answers this question is the proposition of policy. Proposition of policy is a type of proposition used to support a particular course of action. The course of action in the scenario is to persuade the audience to exercise at least three hours a week.
