Explanation

ECC (Elliptic Curve Cryptography) achieves equivalent security strength to other asymmetric algorithms using significantly shorter key lengths. For example, a 256-bit ECC key provides roughly the same security as a 3072-bit RSA key. This makes ECC highly efficient for constrained environments such as mobile devices. Twofish (A) is a symmetric block cipher, not asymmetric. Diffie-Hellman (B) is an asymmetric key exchange protocol but requires large key sizes comparable to RSA to achieve strong security. RSA (D) is a widely used asymmetric algorithm but requires large key lengths (2048 bits or more) to be considered secure, making it less efficient than ECC.
