Extend protection 2 can be accomplished in how many ways?

• A. 4
• B. 2
• C. 3
• D. 5

Answer: (A)

Extending protection to a higher level is about counting all distinct ways to reach that target under the system’s rules. Here, there are four independent, valid methods to achieve the Level 2 extension. Each method represents a unique approach that satisfies the requirements without overlapping with the others, so they all count separately. That combination of four non-overlapping options is why the total number of ways is four.
