What can be true if |a| < |b|, and a > b?

Answer is true lets give numbers to a&b
b<0 a>0
b=-2 a=1
1- (-2)> 1-2
3>-1

|a + b| < a - b

Because the absolute value of a is less than that of b, a is a lesser magnitude than b. However, a > b, so a must be a positive number and b a negative number. So, you can plug in numbers: a = some positive number of magnitude less than b, or a = 3, b = -10. Plug them in, and only B works out.
