A person wearing steel toe capped boots and a person wearing stilleto heels stand on a wooden floor. They both have the same weight. Which person exerts a greater pressure on the floor?

• The person wearing the boots because the boots have a larger surface area in contact with the floor
• The person with the stiletto heels because they have a larger surface area in contact with the floor
• The person wearing the boots because the boots have a smaller surface area in contact with the floor 
• The person with the stiletto heels because they have a smaller surface area in contact with the floor
