Suppose we use a baseball to represent earth. on this scale, the other terrestrial worlds (mercury, venus, the moon, and mars) would range in size approximately from that of view available hint(s)
a) a golf ball to a baseball
b) a dust speck to a golf ball
c) a golf ball to a beach ball
d) a dust speck to a basketball

a golf ball to a baseball

Explanation:

We just need to compare the size of the smallest and the largest one in each group. to make the proper scale comparison.

Mercury's circumference: 15,329 km

Mars' circumference: 21,344 km

(The biggest one on the group approximately 1.4 larger compared to the smallest one in the croup)

Now, see the circumference of the objects on other group:

Dust speck circumference : Too small , impossible to measure

Golf ball circumference:  42.6 mm:

Base ball circumference : 230 mm

Beach ball circumference : 550 mm

Basket ball circumference : 750 mm

There is none among them that has a difference of 1.4 in size, so we need to get the closest one possible.  Which is Golf ball and Base ball.

can you give a picture of the map, i'll be able to update my answer!

answer; i believe the correct answer is (general);
