The provided Json response contains information about different cars. In this data, various car models are listed along with details such as price, year, kilometer, transmission type, color, and more. If you wish to remove any duplicate values related to the fuel type, you need to parse the Json data and filter out repeated fuel types accordingly. Hope this helps!
