Concept: Plagiarism prevention requires awareness, policy, training, checking mechanisms and consistent institutional support.
Step 1: Check Assertion A.
A consistent institutional approach is needed because plagiarism cannot be controlled only by individual effort. Institutions must create rules and awareness.
\[
A = \text{Correct}
\]
Step 2: Check Reason R.
Engaging students and colleagues in discussion about plagiarism is a useful way to build awareness and create a culture of academic honesty.
\[
R = \text{Correct}
\]
Step 3: Check explanation.
Reason R explains one important method through which a consistent institutional approach can be developed.
Therefore, both A and R are correct and R is the correct explanation of A.
