The correct answer is **will be sleeped** (Option 2). **Comprehensive Derivation:** The correct answer is "will be sleeped". Explanation & Key Takeaways: • The error in this sentence pertains to the verb form. • In this sentence, "will be sleeped" is incorrect because "sleeped" is not a correct form of the verb "sleep." • The verb "sleep" is an intransitive verb, which means it does not take a direct object and thus cannot be used in the passive voice (which "will be sleeped" is incorrectly trying to do). • The correct form should be "will be sleeping," which is the future continuous tense of "sleep." • This verb tense is used to describe an ongoing action that will occur in the future. Therefore, the correct answer is "option 2". Thus, the correct sentence should be "The cat will be sleeping comfortably on the windowsill, enjoying the sunshine." **Option Elimination:** • **Option 1 (enjoying the sunshine)**: Incorrect distractor. • **Option 2 (will be sleeped)**: Correct Answer; accurate according to canonical reference. • **Option 3 (on the windowsill)**: Incorrect distractor. • **Option 4 (The cat)**: Incorrect distractor. **Exam Trap:** Be careful of misleading distractors and subtle terminology differences. Verify core properties before selecting your answer. **Memory Booster:** Core mnemonic rule: will be sleeped corresponds to Option (2).
