Answer:

 (B)  4

Step-by-step explanation:

Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...

  3 + 8 = 11

This tells you A = 8, so the top number is 1983, and the middle number is B78.

Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...

  1 + 9 + B = <something ending in 4>

We know the something cannot be 04 or 24, so must be 14. Then ...

  10 + B = 14   ⇒   B = 4

__

So, the whole sum is ...

  1983 +478 = 2461

and the letter values are ...

  • A = 8
  • B = 4
  • D = 2
