The correct answer is "28 + 54".

Solution:
To find the correct answer, we find the sum of each expression by rounding (up or down) the addends.

At Option A:
Round the addends to the nearest tens and then add.

48  +  57  =  ?
↓          ↓
50  +  60  =  110

This expression has a sum nearly equal to 110.

At Option B:

12  +  49  =  ?
↓           ↓
10  +  50  =  60

This expression has a sum nearly equal to 60.

At option C:

74  +  24  =  ?
↓          ↓
70  +  20  =  90

This expression has a sum nearly equal to 90.

At the last option D:

28  +  54  =  ?
↓          ↓
30  +  50  =  80

This expression has a sum nearly equal to 80.

So, the desired answer is "28 + 54".
