Answer:
(c)
Step-by-step explanation:
A alone can complete the work in 16 days.
B alone can complete the work in 12 days
L.C.M of 16 abd 12 is 48 units
So A completes 3 units a day
B completes 4 units a day
And as given A,B and C together completes the work in 4 days. So they completes 12 units a day
So C completes 5 units a day
so C completes the work in 48/5 days.
