I have a Sybex question and need some help
Q) What is risk?
A) Any Potential Occurrence that could cause undesirable or unwanted outcome

 The likelihood that any specific threat will exploit a specific vulnerability to cause harm to an asset.
I think both A and B are correct, but A is more general so I choose A. However the correct answer according to the book is B. Can anyone help me understand why is B and not A.
