Statement — All guilty politicians were arrested. Ranjan and Kamlesh were among those arrested. Question — What follows necessarily?

Introduction / Context:
The stem gives a sufficient condition for arrest within a set: “guilty politicians → arrested.” It does not say everyone arrested is a politician, nor that all politicians are guilty. We must reason about two named arrestees.

Given Data / Assumptions:

• All guilty politicians were arrested.
• Ranjan and Kamlesh are within the arrested set.
• Implicitly, the context concerns politicians (per wording).

Concept / Approach:
If the arrest list is exactly those guilty politicians (standard reading of such items), then being “among those arrested” entails being a guilty politician. The safe necessary inference about the two named individuals is that they were guilty (within the described sweep).

Step-by-Step Solution:

Verification / Alternative check:
On typical exam logic, “all guilty politicians were arrested; X and Y were among those arrested” → X and Y are within the guilty politician set used for arrest.

Final Answer:
Ranjan and Kamlesh were guilty.
