Answer:
The fourth option or monotheism.
Step-by-step explanation:
Monotheism is the belief that there is only one good. Certain branches of Christianity, Islam, and Judaism all believe there is only one God which is the God of Israel. It's not the Torah since the Torah contains the first five books of the Hebrew bible which pertains to Christianity only, it's not the Old Testament because the Old Testament isn't as canon for Islam, and it's also not prophets since all three religions have different views on prophets. Meaning the only relevant answer is that all three religions are monotheistic.
