It looks like the problem is missing the list of possible answer choices for $$ A - B $$. However, I can help you determine all possible values of $$ A - B $$ given that $$ A $$ and $$ B $$ are integers satisfying $$ AB = 20 $$.

Let's list all pairs of integers $$ (A, B) $$ such that $$ A \times B = 20 $$:

1. $$ (1, 20) $$ → $$ 1 - 20 = -19 $$
2. $$ (2, 10) $$ → $$ 2 - 10 = -8 $$
3. $$ (4, 5) $$ → $$ 4 - 5 = -1 $$
4. $$ (5, 4) $$ → $$ 5 - 4 = 1 $$
5. $$ (10, 2) $$ → $$ 10 - 2 = 8 $$
6. $$ (20, 1) $$ → $$ 20 - 1 = 19 $$
7. $$ (-1, -20) $$ → $$ -1 - (-20) = 19 $$
8. $$ (-2, -10) $$ → $$ -2 - (-10) = 8 $$
9. $$ (-4, -5) $$ → $$ -4 - (-5) = 1 $$
10. $$ (-5, -4) $$ → $$ -5 - (-4) = -1 $$
11. $$ (-10, -2) $$ → $$ -10 - (-2) = -8 $$
12. $$ (-20, -1) $$ → $$ -20 - (-1) = -19 $$

From these pairs, the possible values for $$ A - B $$ are:
$$ -19, -8, -1, 1, 8, 19 $$

**If you provide the specific answer choices, I can help identify which of these values is among them.**
Possible values for $$ A - B $$ are -19, -8, -1, 1, 8, and 19.
