In advanced English lexicology, etymology, and orthography, precision in vocabulary requires mastering precise one-word substitutions and recognizing complex spelling conventions. Consider the following four advanced propositions: I. The one-word substitution for 'a government or state ruled by a small group of influential, wealthy, or elite individuals' is accurately designated as an *oligarchy*, whereas government by religious leaders claiming divine mandate is correctly termed a *theocracy*. II. Regarding English orthography and spelling correction tasks involving words prone to suffixation, gemination, and silent letter errors, words such as *millennium*, *accommodation*, *occasional*, and *gauge* contain standard and correct spellings, whereas erroneous variants frequently involve faulty vowel doubling or misplaced consonants. III. The one-word substitution for 'a person who hates, distrusts, or despises humankind in general' is precisely identified as a *misogynist*, whereas a *misanthrope* denotes someone who acts with explicit malice toward state authority. IV. In international English orthography, words of Greek or Latin origin frequently exhibit systematic spelling differences between American (US) and British (UK) standards (e.g., US *program*, *behavior*, *fiber* versus UK *programme*, *behaviour*, *fibre*), where British variants generally preserve historical Anglo-Norman or classical consonant-vowel clusters. Identify the option that correctly evaluates the lexical, orthographic, and semantic validity of propositions I, II, III, and IV according to standard English lexicography and spelling standards.
