You are correct that the flaw in the passage is a whole-part flaw.
The passage concludes that Judge Khalid will be reasonable and fair in deciding the Simdon labour dispute. Why? Because Judge Khalid sat on the panel which resolved the Amlec labour dispute and this panel was reasonable and fair.
Answer choice (B) commits a different error in reasoning. This answer choice uses conditional logic.
Good paediatricians --> Like young children Don't like young children --> Not good paediatrician
This answer choice concludes that, because Alan exhibits the necessary condition (he likes young children), then he will exhibit the sufficient condition (be a good paediatrician). Therefore, the flaw here is that this is an improper reversal, not a whole-part flaw.
