Final answer:
The German couriers in 'Casablanca' were not named in the film, hence none of the options A) Hans and Fritz, B) Karl and Heinrich, C) Otto and Werner, or D) Emil and Kurt are correct.
Step-by-step explanation:
In the classic film Casablanca, the German couriers carrying the letters of transit were not specifically named with first and last names.
The plot revolves around the coveted letters of transit, which have been taken from two murdered German couriers.
The film itself does not focus on the names of these couriers, instead centering on the struggle to possess these documents which allow unrestricted travel through occupied Europe.
The answer to the question provided in the options would therefore be incorrect, as the film does not provide this level of detail about the couriers.
None of the options are correct.
