楼主注意Hence后面的话,逻辑链是:因为A:lock-picking equipment 用于盗窃中,所以B:要再引入restriction。这个A到B的逻辑没有关联,所以正确答案应加强这种关联,即:因为lock-picking equipment 很脆弱很容易坏(则易于被盗)所以要再引入restriction。
鄙人之见~!

Correlation and causation.
The logic of the stimulus is that loosing restriction caused more equipments in the hands of people, and more equipements in the hands of people cause more thefts. Thus, restricting the sale of the equipment would reduce the number of thefts.
What if the same equipment can be used over and over again? Then every thieve could have the perfect tool already and the restriction would not be able to reduce the crime rate. D removes this possibility, thus, strengthen the argument.
