Situation–Reaction (Home Safety)\nYou are alone at home, there is a credible risk of thefts in the area, and you hear a knock at the door. What is the safest immediate action?

Introduction / Context:
Personal security decisions should balance caution with practicality.

Given Data / Assumptions:

• You are alone.

Step-by-Step Solution:

Verification / Alternative check:
Screening preserves safety and still allows legitimate visitors.

Why Other Options Are Wrong:
