Answer is 80.

Explanation:-
The ratio of two numbers = 5: 8 
Let the two numbers be 5 X & 8 X

If their difference is 48, 
8 X – 5 X = 48 
3 X = 48
X = 48/3
X = 16 

Then, the two numbers are 5 X = 16 x 5 = 80  & 8 X = 16 x 8 = 128.

So, the smallest number is 80. 

Hence, the correct answer is option (4) 80.
