Answer:
a is correct because of its Top-down logic
Explanation:
Deductive reasoning is also known as top-down logic, where inductive reasoning refers to bottom-up logic. Top-down logic starts with a theory or premise that is generally assumed to be true, and then moves down all the way to gathering data that confirms or reject the theory.
Taking this in account we can reason that:
b is an example of <em>inductive reasoning</em>
c is subjective reasoning because it´s based on <em>personal </em>observations
d is not reasoning at all because, when confronted with a problem, we should try first to define and analyse it before rushing to collecting data.
e is wrong, that is, when the reasoning I´ve done (a is right and c is wrong) has been correct.
