Consider the definition of the function foo below. Assuming that the next function call to foo would pass the string "\#1,2,3,4,5,6,7,8,9,10\#" (without the quotes) to the parameter y, then which value would need to be passed to foo as the parameter x in order for the return value to be 3 ? def foo(x,y): if x=0: z=ysplit(",") elif x==1: z=ystrip(",") z=zsplit("#") elif x==2: z=ysplit("#") z=z[1]split(",") return len (z) None of these options
