Answer :

In this python code, we uses information supplied in a list called data_set. Each element of data_set is a triple which specifying certain properties for drawing a dot in turtle.

So, the valid values for data_set out of the following data_set is

data_set=[[-50,5,'red'],[-100,10,'blue'],[-200,200,'green'],[-150,-100,'yellow']]

because

(1) If we look at the code , it is given that data[2] store color value .So, data_set third value must store color value .

That why option 1,3,4,6 is not a valid data_set as color value is not always stored in data[2].

Now , we have two option left that is option 2 and 5 where data[2] contain color value.

(2) As it is given in the question that all dot must be done on the left hand side of the canvas that why data[0] will always have negative value and data[1] values can have positive or negative value.

Hence option 2 is the valid data_set for the given python code.
