Akash, who is responsible for grocery shopping, would be tasked with purchasing the food required for the dinner. Bina, who handles cooking duties, would be in charge of preparing the meal for their aunt. Since Chetan is responsible for repairs, ensuring that the dining area is in good repair for the occasion would fall under his responsibilities.

If the oven stops working during meal preparation, it would be Chetan's responsibility to fix it as he handles all repairs within the house. Considering the division of tasks among the siblings, each one would take on their designated role to contribute to the successful hosting of the dinner.

Explain who would be responsible for purchasing the food, who would prepare the meal, and who would ensure that the dining area is in good repair for the occasion. Additionally, if the oven stops working during meal preparation, who would be responsible for fixing it? Respond very briefly.
