The correct example of daily activities involving vector quantities is "Take the elevator to the 20th floor".

Vector quantities are quantities that have both magnitude and direction. In the given options, only "Take the elevator to the 20th floor" involves both magnitude (20 floors) and direction (upwards if going to the 20th floor from a lower floor, or downwards if coming to the 20th floor from a higher floor).

The other options involve scalar quantities, which have magnitude but no direction. Heating food from 27oC to 90oC involves a change in temperature, which is a scalar quantity. Determining the time taken for a race to finish involves time, which is also a scalar quantity. Weighing the fish bought in the market involves weight, which is again a scalar quantity.
