3.

Explanation:

A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface. The armpit of a human and a warm freshwater mud puddle are a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them

the answer is: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall.
