"which hash algorithm's primary design feature is two different and independent parallel chains of computation, the results of which are then combined at the end of the process?
a. sha-384b. hmacc. ripemdd. md5"

Option C i.e., RIPEMD is the correct option for the following question.

Explanation:

Because RIPEMD is the algorithm that is used for the hash primary design characteristic which has two independent and unlike parallel chains of the calculation and computation and the outputs of which are then linked to the process at the end. It is also used for the safe process of replacing the 128-bit hash method.

Other options are wrong because these are not related to the following statement.
