Final answer:
The correct answer is option C) The harsh natural environment and primitive living conditions.
Step-by-step explanation:
In Aldous Huxley's Brave New World, Bernard and Lenina are disturbed by the Indians' way of life and environment primarily because of the harsh natural environment and primitive living conditions. The Indians lack the comforts and conveniences that Bernard and Lenina are accustomed to in their highly technological society, including advanced medical care.
Additionally, the Indians' strong connection to nature and community, along with their use of rituals and celebrations, starkly contrasts with the controlled, uniform world Bernard and Lenina come from, where individuality is suppressed for the sake of maintaining societal order.
