The question is wrong.
If A and B are independent, then P(A) = P(A | B).
========================================
If this is really what you see from the question, then I think you can only answer D.
There are 4 options.
A. 0.36
B. 0.60
C. 1.20
D. Cannot be determined from the information given.
However, please keep in mind that the fact is MORE than "Cannot be determined from the information given".
The fact is "the given pieces of information are inconsistent".
