The Fire Sprinkler Initiative, which advocates the use of sprinkler systems, makes many statistics available on its website. For example, the site explains that a person has a 99.45 percent risk of surviving a house fire with a smoke alarm and a 98.87 percent chance without it. A reasonable conclusion, therefore, is that the use of smoke alarms does not merit their cost.
The conclusion drawn by the writer depends on which of the following assumptions?
(A) Using sprinkler systems makes more sense than using smoke alarms does.
(B) A small percentage of deaths due to not using alarms is acceptable.
(C) A decrease of just under 1% could translate to many avoidable deaths.
(D) Sprinkler and smoke detection systems offer negligible lifesaving benefits.
(E) The difference is not statistically significant because of a 1% error rate.

The answer should be B.
A, D and E are cancelled because out of context.
when you negate C and B. B comes out to be a clear answer

Official Explanation
The argument relies on the assumption that percent ages alone matter, and not the actual number of deaths represented by those statistics. (Some would say that any life, let alone multiple lives, saved by alarms validates the cost of the alarms; assuming this is a national statistic, it could imply scores of lives.) Choice (B) explicitly states an underlying assumption that leads to the conclusion.
The correct answer is (B).
