In a multilingual and diverse English language classroom, educators frequently encounter various forms of learner errors and language difficulties stemming from native language interference, developmental staging, or overgeneralization. Consider the following advanced pedagogical propositions regarding error analysis and language difficulties in a diverse classroom:I. Interlingual errors are caused by the transfer of grammatical, phonological, or lexical patterns from the learner's mother tongue (L1) to the target language (L2), often manifesting as negative transfer or interference.II. Intralingual and developmental errors occur due to the misleading overgeneralization of target language rules (e.g., applying regular past-tense '-ed' to irregular verbs like 'goed'), which are a natural and necessary part of the hypothesis-testing process in second language acquisition.III. According to modern error analysis theory pioneered by S. Pit Corder, learner errors should be treated exclusively as moral failures or behavioral shortcomings that must be immediately and harshly eradicated through punitive drills to prevent fossilization.IV. Fossilization refers to the process whereby incorrect linguistic forms become permanently entrenched in a learner's interlanguage system, even after years of advanced instruction or prolonged exposure to the target language.Identify the option that correctly evaluates the pedagogical and linguistic validity of propositions I, II, III, and IV.
