#1**+10 **

Mmm

Well there are far more dots to the right of 244 ft than to the left so that is not a median height.

So it is not either of the first two

39000f^3 has lots more dots below than above so its not the last one

That leaves you with C or d.

Just count the dots. There has to be the same number above as below

and

the same number on the left as on the right. :)

It is a good question :)
