First of all thanks for this repo and content. The best prep material for CCDAK exam.

Q24 from Broker section link is misleading and needs to be reframed.
Kafka documentation mentions that precedence order is of log.retention. is determined by units in the property name itself rather than the actual values for these properties.

Kafka documentation states that log.retention.minutes is secondary to log.retention.ms and log.retention.hours is tertiary to log.retention.ms.

Precedence Order regardless of values is
log.retention.ms > log.retention.minutes > log.retention.hours

Option A & B can be tweaked to be more implicit and remove ambiguity. And accordingly explanation can be tweaked as well.
A. The larger unit value will take precedence
B. The smaller unit value will take precedence
