Final answer:
The correct option is a. Religion and cuisine are two aspects that do not unite India; they reflect the country's diversity in faiths and culinary practices.
Step-by-step explanation:
Aside from language, two aspects that often unite a nation but do not unite India are religion and cuisine. While religion can be a powerful unifying force, India is a religiously diverse nation with significant Hindu and Muslim populations, among others, and experiences ongoing conflicts along religious lines. Additionally, cuisine in India is incredibly diverse with clear distinctions between the foods of the north and the south, and between vegetarian and non-vegetarian diets, influenced by religious beliefs. Therefore, the correct answer is a) Religion and cuisine.
Food is a deeply ingrained part of cultural identity, often closely tied to the traditions and living habits of a community. In India's case, the variety in cuisine reflects the country's rich tapestry of cultures and is linked to different religious practices and regional preferences. Similarly, religion in India does not act as a central unifying factor due to the multitude of faiths practiced within the nation's borders.
