Final answer:
Without context from Part A, Option D may be the strongest support as it involves a definitive action that could be linked to an assertion made in Part A.
Step-by-step explanation:
To determine which evidence from the passage most strongly supports the answer in Part A (the provided answer for Part A is needed for context), one must analyze the given options and find the one that best correlates with the main claim or answer from Part A. Since the answer to Part A is not provided, we can review the evidence options by their content. Option A (Celestial music) and B (Approach! thy soul shall into raptures rise!) contain elements of persuasion and allure. Option C (We know whate'er the kings of mighty name) refers to knowledge of past deeds, while Option D (Then scudding swiftly from the dangerous ground) describes an action taken to avoid danger.
Without the specific context of Part A, it is challenging to select the most appropriate evidence. However, among the options, Option D stands out as it indicates a definitive action (the chains unbound), which could be a result or consequence that supports an assertion or claim made in Part A. Hence, if Part A involves an action or decision made by a character, Option D could be the strongest support.
