The correct answer is: C. crowded
Diwali is a major Hindu festival of lights, which is celebrated every year in the month of November. It is a time for people to come together and celebrate the victory of good over evil, light over darkness, and knowledge over ignorance.
During Diwali, people decorate their homes with lights and rangolis (colorful patterns made on the ground with rice flour or sand). They also exchange gifts and sweets, and visit family and friends.
Shops are usually crowded during Diwali, as people buy gifts, sweets, and decorations for the festival. The streets are also crowded with people, as they go to temples to pray, or to visit family and friends.
The other options are not as accurate as “crowded”. “Busy” could refer to any time of year, and does not specifically refer to Diwali. “Full” could refer to a shop that is stocked with goods, but it does not necessarily mean that the shop is crowded with people. “Bubbling” is not an accurate description of a shop during Diwali.
