Read these lines: "When a woman thinks that her house is on fire, her instinct is at once to rush to the thing which she values most. It is a perfectly overpowering impulse, and I have more than once taken advantage of it." According to the quoted lines, why was the alarm of fire raised?

1. The speaker states a rule he trusts: a woman who thinks the house is burning runs to what she values most. 2. He then says he has more than once taken advantage of that impulse. 3. Taking advantage of it means watching where she runs, which shows him the hiding place. 4. So the alarm was raised to send her straight to her most prized possession, option C. 5. Searching every room is ruled out by the whole point of the trick, which is to be shown the spot rather than hunt for it. _Source: Arthur Conan Doyle, The Adventures of Sherlock Holmes (1892), A Scandal in Bohemia_
