Read the passage and answer the following question:

Consumer Protection and Consumer Rights in India

Ananya recently purchased a refrigerator from a well-known electronics store in her city. The salesperson assured her that the product came with a one-year warranty and free servicing. However, within two months, the refrigerator started making loud noises and failed to cool effectively. When Ananya contacted the store, the manager refused to honor the warranty and demanded additional payment for repairs.

Feeling cheated, Ananya decided to exercise her consumer rights. She researched the Consumer Protection Act, which provides a legal framework for addressing consumer grievances in India. Ananya learned about her rights, including the right to safety, the right to information, and the right to redressal.

She first wrote a formal complaint to the store, attaching a copy of the purchase receipt and warranty card. When the store did not respond, Ananya escalated the matter by filing a complaint with the District Consumer Disputes Redressal Commission (DCDRC). She submitted all necessary documents and explained how the store had violated her rights.

The DCDRC found the store guilty of unfair trade practices. The commission ordered the store to repair the refrigerator free of charge and pay Ananya compensation for mental harassment.

What violation was the store found guilty of?

Unfair trade practices

The correct answer is Option 3: Unfair trade practices

The final sentence of the third paragraph explicitly states: "The DCDRC found the store guilty of unfair trade practices." This encompasses the refusal to honor the warranty and demanding extra payment for repairs of a defective product.
