A,B Correct answer
Explanation

Both 'I am not able to' and 'I am unable to' are grammatically correct ways to express inability. 'Unable' is the direct negative of 'able', while 'not able' uses the negation. Options C and D incorrectly use 'able' with 'didn't' and 'won't' - it should be 'wasn't able to' and 'won't be able to'.
