The "tool" function of theory is to: (a) Summarize existing knowledge

(b) Summarize existing hypotheses

(c) Suggest new relationships and make new predictions

(d) Suggest new theories

✅ Correct option: (c) Suggest new relationships and make new predictions

Explanation (200+ words):

One of the most important functions of a theory is its tool function, which allows researchers to generate new hypotheses, suggest relationships between variables, and make predictions that can be empirically tested. While theories do summarize existing knowledge, their primary value lies in guiding future research. A good theory helps researchers decide what to study next, how variables might be related, and what outcomes can be expected. Option (a) refers more to a review of literature than a tool function. Option (b) is incorrect because theories do not merely summarize hypotheses; they help create them. Option (d) is also incorrect because theories do not mainly exist to suggest new theories. Therefore, option (c) is the correct answer.
