下面代码自定义了一个函数，实现以(100,50)为初始坐标，绘制边长为50的红色正方形，选项中正确调用函数的是()
import turtle as t def draw_square(a,b,c,d,e): t.penup() t.goto(a,b) t.pendown() t.color(c) for i in range(e): t.forward(d) t.left(360 / e)
draw_square(100,50,'red',50,4)
draw_square(100,50,'red',50)
draw_square(50,100,'red',50,4)
draw_square()
