Solution

The correct option is C six floors
Naman is on the 5th floor,
It can represented as +5 .
Parking lot is in one floor below the ground floor.
If we take the ground floor as zero , hence parking lot can be represented as -1

To get the number of floors he has to come down, we have to subtract

We get 5 - (-1)
= 5 + 1
= 6

Naman has to come down 6 floors to get his car from the parking floor/area.
