Topic: Conjugation of Verb,

Best Answer Explained in Below-:

The correct answer to the question regarding the past participle form of "slay" is B) slain. Understanding verb forms in English involves recognizing how irregular verbs change through different tenses. In this case, "slay" is an irregular verb that does not follow standard conjugation patterns.

In English, the verb "slay" means to kill or destroy in a violent manner. When conjugating this verb in the past tense, it transforms to "slew," which is the simple past form. However, when we need to use the past participle, which is often used in perfect tenses or passive voice constructions, the verb changes again and becomes "slain."

Other options provided can be clarified as follows: "slane" is not a recognized form, "slyed" is a misformation, and "slew" is indeed the simple past but not the past participle. Therefore, "slain" is the appropriate choice and reflects the correct grammatical structure used in English. For example, in the sentence "The dragon was slain by the knight," "slain" correctly serves as the past participle.
