In the Suniti Building in Mumbai there are 12 floors plus the ground floor. People get into the lift on the ground floor, the lift does not stop on the first floor. If 2,3 and 4 people alight from the lift on its upward journey, then in how many ways can they do so? (assume they alight on different floors)
A)C(11,3)*P(3,3)
B)P(11,3)*C(9,4)*C(5,3)
C)P(10,3)*C(9,4)*C(5,3)
D)C(12,3)
