如图所示python程序，下列操作哪个能实现：程序不报错，仅中间红色虚线框中部分不运行？（ ）
import turtle turtle.pendown() turtle.forward(150) turtle.left(120) ''' turtle.forward(150) turtle.left(120) """ turtle.forward(150) turtle.left(120) turtle.penup()
import turtle turtle.pendown() turtle.forward(150) turtle.left(120) ''' turtle.forward(150) turtle.left(120) ''' turtle.forward(150) turtle.left(120) turtle.penup()
import turtle turtle.pendown() turtle.forward(150) turtle.left(120) ### turtle.forward(150) turtle.left(120) ### turtle.forward(150) turtle.left(120) turtle.penup()
import turtle turtle.pendown() turtle.forward(150) turtle.left(120) ,,, turtle.forward(150) turtle.left(120) ### turtle.forward(150) turtle.left(120) turtle.penup()
