23. The most secure places to hide have the following in co mmon except A. is secured by a locking mechanism that keeps the attacker away. B. has furniture that may be used to barricade the door. C. has furniture or objects that provide additional concealment. D. is secured behind a door that opens inwards into the room.

The correct answer is D. is secured behind a door that opens inwards into the room.<br /><br />Explanation:<br />The most secure places to hide typically have certain features that make them difficult for an attacker to access or find. Let's analyze each option:<br /><br />A. is secured by a locking mechanism that keeps the attacker away: This is a common feature of a secure hiding place, as it prevents the attacker from easily opening or entering the hiding spot.<br /><br />B. has furniture that may be used to barricade the door: Furniture such as chairs or tables can be used to block the door and make it more difficult for the attacker to force it open.<br /><br />C. has furniture or objects that provide additional concealment: Having furniture or objects in the hiding spot can help to camouflage it and make it less noticeable to the attacker.<br /><br />D. is secured behind a door that opens inwards into the room: This is not a common feature of a secure hiding place. In fact, a door that opens inwards can make it easier for the attacker to access the hiding spot, as they can simply open the door and enter the room. Therefore, this option is the exception among the common features of a secure hiding place.
