Explanation
Option B is correct because the port numbers in the statement are reversed. In CAPWAP, UDP port 5246 is assigned to control messages, and UDP port 5247 is assigned to data messages - the opposite of what the question claims. Option A is wrong because accepting the swapped values would reflect a fundamental misunderstanding of the CAPWAP standard as defined in RFC 5415.
Memory tip: Remember the order alphabetically - Control comes before Data, and 5246 comes before 5247, so Control gets the lower port (5246) and Data gets the higher port (5247).
