Claim

Sonam Wangchuk is 'no Phunsukh Wangdu' — that his scientist credentials are a myth and he is disqualified as the son of a Congress leader.

Rationale

An ad hominem that substitutes personal delegitimisation for engagement with the exam-integrity demand. Wangchuk's engineering/education-reform work and his widely-reported role as an inspiration for the '3 Idiots' character are matters of public record; political parentage is not a rebuttal of the protest's substance.
