Answer:
The correct answer is D - ‘practices that link Jews’
Explanation:
Eating kosher food. Judaism as a religion has a <em>group of dietary laws called Kashrut</em>, while the foods cooked according to these laws are called kosher. In particular, detailed Kashrut rules apply to animal-based ingredients in order to cook Kosher foods.
Celebrating Yom Kippur. Yom Kippur is a <em>Day of Atonement</em> and one of the central and most important holy days in Judaism. On that day Jewish people spend about 25 hours fasting. They also attend synagogue and pray vigorously.
Attending a synagogue. The synagogue is the <em>main institute</em> in the Judaism religion. It is a physical space, in which Jewish people assemble for prayer and other religious services. The synagogue is also a central point in the religious life of a Jewish community.
Reading the Torah. Torah in its broader meaning as a <em>collection of written and spoken laws of Judaism as a religion</em>. Reading and studying Torah is a holy responsibility of every Jew. If a person that identifies with Judaism is unable to study Torah regularly, this person should, by all means, support those who do study Torah.
