The correct answer is: B. crowded
During Diwali, the shops are crowded with people. This is because Diwali is a major festival in India, and people often go shopping for new clothes, gifts, and decorations for the festival. The shops are also crowded because people are buying food and other items to celebrate the festival.
The other options are not as accurate as “crowded.” Option A, “busy,” could be used to describe the shops at any time of year, but it does not specifically capture the sense of excitement and anticipation that is present during Diwali. Option C, “full,” could also be used to describe the shops at any time of year, but it does not convey the sense of congestion and lack of space that is present during Diwali. Option D, “bubbling,” is not an accurate description of the shops during Diwali.
