B Correct answer
Explanation

ARM processors support multiple addressing modes. Unlike some microcontrollers that are strictly byte-addressable, ARM can address bytes (8-bit), half-words (16-bit), and words (32-bit). The term 'Half-word or Full-word Addressable' refers to this ability to efficiently access different data sizes. ARM is byte-addressable at its core but supports aligned accesses to half-words and full-words. The claimed answer captures this multi-width addressing capability.
