Answer: A. Two (Lossy and Lossless)

Answer: A) Two (Lossy and Lossless)
Explanation: Compression techniques are divided into two fundamental classes: Lossless (allowing bit-perfect original reconstruction, crucial for source code/text) and Lossy (eliminating non-essential data that human senses cannot easily detect, ideal for media).
