ANSWER:
C. A woman standing in high-heel shoes.
Explanation:
The pressure is given by the force per unit area, that is to say, the greater the area the pressure is less in the same way that the smaller the area, the pressure is greater.
Therefore, the shoes with a smaller area, that is, the high-heel shoes, will exert more pressure.
Therefore, the correct answer is C. A woman standing in high-heel shoes.
