Which term refers to words that have different spellings but share the same pronunciation and differ in meaning?

Explanation

Homophones are words that sound identical when spoken but have different spellings and meanings. For example, 'flower' and 'flour' are homophones. Allophones relate to variations in phonemes, homographs are words spelled the same but pronounced differently, and homonyms can refer to words that are either homophones or homographs.
