What is the nature of translation? ( )

A、If "translation"refers to a subject,namely,the study of translation theory and skills,it is no doubt a ascience with its own rules,laws and priciples for the translators to abide by.
B、If it refers to a process,then we may regard it as a craft or skill.For unlike any branch of natural science,the process of translation has its peculiarity,and none of its rules and priciples is universally applicable/
C、If it refers to some specific pieces of translation,then it is more like an art,with each piece manifesting its own charms and style in the creative hands of the translator.
D、Translation is a ascience,an art,a skill,a craft,an operation or a kind of communication.
