Step 1: Understand analogy.
We are given: References : ........... :: Guidelines : Implement.
This means we must find a word that has the same relationship with "References" as "Implement" has with "Guidelines".
Step 2: Relationship between Guidelines and Implement.
Guidelines are something that are implemented.
So the analogy is: "What do you do with references?"
Step 3: Analyze options.
- (A) Sight → means vision, not related. Incorrect.
- (B) Site → place, unrelated. Incorrect.
- (C) Cite → to mention/refer to a source. Correct, because you cite references.
- (D) Plagiarise → copying without credit, opposite meaning. Incorrect.
Step 4: Correct analogy.
References : Cite :: Guidelines : Implement.
Final Answer:
\[
\boxed{\text{Cite}}
\]
