Final answer:
Option C). The strength of a password hash is determined by the hashing algorithm used, as well as the length and complexity of the password. A strong hashing algorithm makes it difficult for attackers to reverse-engineer the original password from the hash. A longer and more complex password generally results in a stronger hash that is harder to crack.
Step-by-step explanation:
The hashing algorithm used, together with the length and complexity of the password, determines how strong the hash is. The password is transformed into a fixed-length string of characters by the hashing algorithm. It is more difficult for attackers to deduce the original password from the hash when the hashing algorithm is strong. The strength of the hash is also influenced by the password's length and complexity. Stronger and more difficult to crack hashes are typically produced by longer, more complicated passwords.
