Hashing Mining Uses

Multiple Choice

Hashing Mining uses:

A) Keccack256 while internally to hash values it's easy to use the Dagger-Hashimoto to create a meaningful hash.
B) the Dagger-Hashimoto hashing while internally the EVM uses SHA256 which is an alias for Keccack256.
C) the Dagger-Hashimoto hashing while internally the EVM uses Keccack256 which is almost similar to SHA256, but has a different padding so produces different hashes.
