在数控程序中，G指令和M指令的作用分别是什么？

A. price = {'苹果':5.5,'香蕉':2,'橘子':1.5,'葡萄':8,'梨':6.5}
B. price = dict(苹果=5.5,香蕉=2,橘子=1.5,葡萄=8,梨=6.5)
C. tuple_fruit =['苹果','香蕉','橘子','葡萄','梨']list_fruit = [5.5,2,1.5,8,6.5]price =dict(tuple_fruit,list_fruit)
D. tuple_fruit =['苹果','香蕉','橘子','葡萄','梨']list_fruit = [5.5,2,1.5,8,6.5]price =dict(zip(tuple_fruit,list_fruit))
