Explanation:

We have to pick the choice that is not the cause behind the rise in piracy. 1 goes out because it is the cause. The first sentence of the fourth paragraph offers the clue. The third paragraph says that “the main motive for piracy has always been a combination of need and greed...”. Thus 3 also is correct, as a cause of piracy. The fourth paragraph has clue to option 4 as well. Thus 2 is the right choice. The author believes that surveillance can never be an effect solution because it is not addressing the root cause.

Hence, option (b) is correct.
