d. Provides a stronger cryptographic result with a shorter key.
Explanation:
The elliptic curve cryptosystem (ECC) is a public key cipher that provides higher security than other public key cryptosystems, such as the RSA, with shorter key.
So the correct answer is:
d. Provides a stronger cryptographic result with a shorter key.
