Answer:
C. Judaism
Step-by-step explanation:
Jesus of Nazareth practiced the religion of Judaism while he was alive. Jesus was born into a Jewish family and grew up following the teachings and customs of Judaism. He studied the Torah (the Jewish holy book) and participated in Jewish rituals and ceremonies.
Throughout his ministry, Jesus often quoted from the Hebrew Bible and taught in synagogues, which were Jewish places of worship. He observed Jewish festivals such as Passover and Hanukkah, and he followed Jewish laws and traditions.
It's important to note that Christianity, the religion that developed after Jesus' death, emerged as a separate faith from Judaism. However, during his lifetime, Jesus identified himself as a Jewish teacher and his teachings were rooted in Jewish scripture and beliefs.
In summary, Jesus of Nazareth practiced the religion of Judaism during his lifetime.
