Which of the following best describes the author's use of deductive
reasoning?

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I can only help you in a general way. In logic, arguments are divided two broad categories:

1. Inductive arguments:  This type of arguments is intended to show that if all the premises are true, the conclusion is probably or likely true, that is, it is not certainly true. So an argument like this just tells us about the probability of being true.

2. Deductive arguments: On the other hand, this type of arguments provides complete certainty and tells us that if all the premises are assumed to be true, then the conclusion must be true.

For example:

PREMISE 1: All babies are human being.

PREMISE 2: All human beings have emotions

CONCLUSION: Therefore, certainly all babies have emotions
