A dry sanitizer is effective when:

the door is kept open
it contains an active fumigant
it contains hot steam
it contains a deodorant

The correct answer is: it contains an active fumigant

A dry sanitizer is effective when it contains an active fumigant. This is because the purpose of a dry sanitizer is to kill germs and bacteria on surfaces, and an active fumigant is a chemical that is able to do so effectively. The other options, such as keeping the door open or using hot steam, may have some impact on sanitation, but they are not directly related to the effectiveness of the sanitizer. Using a deodorant may make the surface smell better, but it does not necessarily mean that it is clean and sanitized. Therefore, the correct answer is B.
