A latch jamb is most commonly found on which of the following?

A latch jamb is a component that is specifically designed to secure a door in place, providing a point for the latch bolt to engage when the door is closed. It is an integral part of the door frame, ensuring that the door is properly aligned and can be locked effectively. The latch jamb allows the door to operate smoothly while maintaining its security and preventing unwanted access.

In contrast, while windows, gates, and cabinets may have locking mechanisms, they do not typically utilize a latch jamb in the same way as doors do. Windows may use different types of latches or locks that do not involve a jamb, gates may have hinges and different locking structures, and cabinets usually incorporate internal mechanisms that are not referred to as a jamb. Thus, the specific association of a latch jamb with doors underlines its function and design within typical door installations, making it the correct answer.
