The process of word formation consists of

Word formation involves creating new words from existing ones through various processes. Compounding combines two or more words to form a new word (like 'sunflower' from 'sun' + 'flower'). Conversion is changing a word's part of speech without adding affixes (like 'email' as noun becoming 'to email' as verb). These are two fundamental processes in word formation. Option A correctly identifies both processes. Option D is incorrect because using synonyms doesn't form new words, and Option B is partially correct but incomplete.
