I found the answer A quite confusing given the following scenario:

Current scenario:

------------------------Fast dialing---Slow dialing---Total

Price per customer-------10---------------8

Cost per customer--------5----------------6

profit per customer-------5----------------2

# of customers-----------3----------------7---------- 10

Total profits--------------15---------------14----------29

New scenario: all customers switch to FD at revenue of 8$ per customer

Cost per customer-------5

profit per customer------3

# of customers----------10

Total profits--------------30

So basically in this scenario, the proposal to switch all customers to FD would increase totalprofits
