The correct option is (B): Bhushan
Explanation: If Pramila did not participate in the interview, Unni, being an expert in Basic Sciences, would most likely be paired with someone from Social Sciences, as each panel needs representation from both areas. Since Cyriac cannot be paired with Ram, and Pramila is not participating, Bhushan, being a Social Sciences expert, is the most likely person to be with Unni. Hence, the correct answer is Option B – Bhushan.
