_____ is the process of converting something from one representation to the simplest form. It deals with the way in which systems convert data from one form to another.

A.
Canonicalization

B.
Character Mapping

C.
Character Encoding

D.
UCS transformation formats

Explanation:
Canonicalization (abbreviated c14n) is the process of converting data that has more than one possible representation into a "standard" canonical representation. This can be done to compare different representations for equivalence, to count the number of distinct data structures (e.g., in combinatorics), to improve the efficiency of various algorithms by eliminating repeated calculations, or to make it possible to impose a meaningful sorting order.
