Final answer:
The latest driver for a video card should be obtained from the manufacturer's website to ensure you are getting the most recent and official version. Using a CD-ROM, friend, or relying solely on Microsoft's Windows Update might result in outdated or incorrect drivers.
Step-by-step explanation:
The best place to get the latest driver for a video card is D. Manufacturer's website. It is important to keep video card drivers updated for optimal performance and to benefit from bug fixes and new features that the manufacturer may offer. When you download drivers directly from the manufacturer's website, you are ensured to receive the most recent and official version that is compatible with your hardware.
Other sources, such as a CD-ROM, may contain outdated drivers, and relying on a friend for drivers is risky because they may inadvertently provide you with incorrect or outdated software. Microsoft's Windows Update service may offer some driver updates, but it does not always have the latest version that the manufacturer has on their site.
