Explanation

This answer is correct because DES (Data Encryption Standard) is the least secured encryption algorithm among the options given. DES uses a 56-bit key, which is too short and can be easily cracked by brute force attacks. DES also suffers from other weaknesses, such as weak keys, complementation property, and linear cryptanalysis. The other answers are not correct because they are more secured encryption algorithms than DES. 3DES (Triple DES) is an improvement over DES that applies DES three times with different keys, resulting in a 168-bit key. AES-128 and AES-256 are variants of AES (Advanced Encryption Standard) that use 128-bit and 256-bit keys respectively. AES is considered to be the most secure symmetric encryption algorithm and is widely used for data protection.
