A.
It converts a message of arbitrary length into a value of fixed length.

B.
Given the digest value, it should be computationally infeasible to find the corresponding message.

C.
It should be computationally infeasible to derive the same digest from two different messages.

D.
It converts a message of fixed length to an arbitrary length value.

Explanation:
A hashing algorithm will take a string of variable length, the
message can be of any size, and compute a fixed length value. The fixed length value
is the message digest. The MD family creates the fixed length value of 128 bits and
SHA creates one of 160 bits.
Although the message itself is not really converted into any other format, as with
encryption, this is the terminology you might see.
