A,B,C Correct answer
Explanation

Hash, Modulus, and Range are all key-based partitioning methods that use key values to determine partition assignment. Hash uses hash function on key, Modulus uses key value modulo partition count, Range uses key value ranges. DB2 uses DB2's algorithm which is also key-based but often treated separately in documentation.
