A Correct answer
Explanation

3DES applies the DES algorithm three times to each data block, effectively increasing the key size and making brute-force attacks much harder. While DES uses a 56-bit key, 3DES can use up to 168 bits (though effective security is 112 bits due to meet-in-the-middle attacks). This triple encryption provides significantly stronger protection against cryptanalysis than single DES.
