The diagram shows an athlete doing press-ups on a floor. The athlete is using both hands. The area of contact of each hand with the floor is S. The athlete's toes act as a pivot during each press-up. The athlete's weight W acts through point X. The distance between his toes and point X is three quarters of the distance between his toes and his shoulders. What is the pressure exerted on the palm of each of the athlete's hands?

1. A\frac{W}{8S}
2. B\frac{3W}{8S}
3. C\frac{W}{4S}
4. D\frac{3W}{4S}
