What is the correct way to reply “What is the most expensive food in the market”?
Should I say:
- The most expensive food is banana.
- The banana is the most expensive food.
- A banana is the most expensive food
All of your answers are grammatical, and would work for a formal question.
Using a singular (banana) instead of a plural (bananas) is a little unusual, as people rarely buy a single banana. The sign at my grocery store uses the plural and says "Bananas 49¢ / pound."
The most common way to respond is simply to name the item:
Bananas.
However, in many markets, bananas are inexpensive. So the correct answer might be
Wagyu beef is the most expensive food.
