阅读下面程序:li_one = ['p','c','q','h']li_two = ['o']li_one.extend(li_two)li_one.insert(2,'n')print(li_one)运行程序,输出结果正确的是()
A: ['p','c','n','q','h','o']
B: ['p','c',h','q','n','o']
C: ['o','p','c','n','q','h']
D: ['o','p','n','c','q','h']
A: ['p','c','n','q','h','o']
B: ['p','c',h','q','n','o']
C: ['o','p','c','n','q','h']
D: ['o','p','n','c','q','h']
