Answer 1

The correct answer is Using a mantrap.

A mantrap is a security feature that consists of two interlocking doors that prevent unauthorized access to a secure area. The first door must close before the second door can be opened, allowing only one person to enter at a time and providing a secure way to control access to a secure area from a nonsecured area.
