Which of the following software types BEST facilitates collaboration?

Personal information managers (PIMs) help organize individual schedules and contacts, which supports personal productivity, not direct group collaboration.

Video editing software is a specialized tool for creating and manipulating video content, not inherently designed for general team collaboration.

Instant messaging software allows for real-time, synchronous communication and quick exchange of text, files, and even screen sharing, making it highly effective for direct collaboration among team members. Its immediate nature streamlines communication and decision-making processes, directly supporting collaborative workflows.

CAD (Computer-Aided Design) software is used for designing and drafting, which can be part of a collaborative project but is not a general-purpose collaboration tool itself.
