Which of the following consumer grievance redressal agencies would handle consumer disputes amounting between rupees 20 lakh and 100 lakh?

The correct answer is: B. State Commission

The Consumer Protection Act, 1986 provides for a three-tier redressal mechanism for consumers. The first tier is the District Forum, which can entertain complaints where the value of the goods or services involved is up to Rs. 20 lakhs. The second tier is the State Commission, which can entertain complaints where the value of the goods or services involved is more than Rs. 20 lakhs but less than Rs. 1 crore. The third tier is the National Commission, which can entertain complaints where the value of the goods or services involved is more than Rs. 1 crore.

Zila Parishad is a local self-government body in India. It is not a consumer grievance redressal agency.
