Final answer:
The statement is False. The Ramayana is primarily revered in Hinduism and is not widely revered by Jains, Buddhists, and Muslims.
Step-by-step explanation:
The statement is False.
While the Ramayana is considered a revered text in Hinduism, it is not revered by Jains, Buddhists, and Muslims as claimed by Prothero. The Ramayana is specific to Hinduism and its influence is primarily within the Hindu community.
Moreover, when considering the most influential books, it is important to note that influence can be subjective and vary across different cultures and religions.
