How does ElGamal Digital Signatures differ from the more commonly used RSA signatures?

Select one:

a$.$ ElGamal signatures provide stronger non$-$repudiation, while RSA signatures prioritize efficiency.

b$.$ RSA signatures are vulnerable to attacks exploiting specific weaknesses in its mathematical foundation.

c$.$ ElGamal involves additional computations compared to RSA, making it less suitable for high$-$volume signing.

d$.$ Both rely on the same mathematical principle but offer different levels of security.
