27:汉客笔记给的C
M-W中的解释如下：
ORIGINAL的含义是:
1 : of, relating to, or constituting an origin or beginning : INITIAL *the original part of the house*
2 a : not secondary, derivative, or imitative  b : being the first instance or source from which a copy, reproduction, or translation is or can be made
3 : independent and creative in thought or action : INVENTIVE
而BASIC的含义是：
1 : of, relating to, or forming the base or essence : FUNDAMENTAL
2 : constituting or serving as the basis or starting point
RUDIMENTARY的含义是：
1 : consisting in first principles : FUNDAMENTAL *had only a rudimentary formal education D. J. Boorstin*
2 : of a primitive kind *the equipment of these past empire-builders was rudimentary A. J. Toynbee*
3 : very imperfectly developed or represented only by a vestige *the rudimentary tail of a hyrax*

M-W:

这样看来还是C好些
