Step 1:
Let me solve this problem step by step:

Step 2:
: Understand the Context

This is a calibration question related to thermometers. Calibration ensures accurate temperature measurement.

Step 3:
: Analyze the Options

A. Drops to the floor - This is not a standard calibration trigger B. Submerges completely in water - This is a key calibration method C. Comes into contact with an allergen - Not related to calibration D. Falls in the soup - Not a calibration procedure

Step 4:
: Recall Calibration Principles

Calibration of thermometers typically involves: - Using a known reference temperature - Ensuring accurate readings - Verifying instrument precision

Step 5:
: Identify the Correct Answer

Submerging a thermometer completely in water allows calibration at the freezing point ($$0^{\circ}C$$ or $$32^{\circ}F$$).
The correct answer is B.

Step 6:
: Explain the Reasoning

When a thermometer is fully submerged in pure water at standard atmospheric pressure, it can be adjusted to read $$0^{\circ}C$$ (freezing point), which is a standard calibration reference point.

Final Answer

Submerges completely in water
