• C. A method for compressing video.
• D. A protocol for secure video streaming.

Answer: (A)

Deepfake refers to synthetic media created with artificial intelligence in which a person in an image or video is replaced with someone else’s likeness. This effect is usually produced with deep learning models, such as GANs or autoencoders, that learn to map one face onto another and blend it into the footage. The result can look very convincing, which is why deepfakes raise concerns about misinformation and manipulation, though they’re also used for entertainment and parody. The other options describe encryption, compression, or secure streaming—topics that are unrelated to generating altered images or videos of people, so they don’t fit the concept of a deepfake.
