Final answer:
Jewish morality has changed over time, evolving through discussions, debates, and reinterpretations while preserving its core teachings from the Torah and Talmud.
Step-by-step explanation:
Based on the information provided, one can conclude that Jewish morality has changed over time (Option B). Jewish ethical rules and morals have been discussed, debated, added to, and considered over the millenia. This evolutionary characteristic of Jewish ethics signifies that, while the core teachings from the Torah and Talmud have been preserved, interpretations and applications have adapted through the ages. This includes the development of an egalitarian ethical system, strict religious customs, and observances such as dietary laws. Notably, the commitment to live moral lives and closely follow the laws of Moses has been a consistent element of Jewish morality.
