It doesn't seem to be A or C because the slope doesn't look that steep.
After estimating we can see that the slope of B still looks too steep, so I'd say D.
To check, you can see the y-intercept is around 20 and the slope is about 1.
You are very welcome!
This won't be precise....but...It appears that the y intercept would be at ≈ 20
So.....we only have two equations to consider
y = x + 20
y = 2x + 20
Note that the last data point on the right has a y value of ≈ 65
And the x value associated with this point ≈ 20
And assuming that a line of best-fit might pass through the second data point from the left
The coordinates of this point ≈ (2.5, 25)
So....the slope of the line is ≈ [ 65 - 25 ] / [20 - 2.5] ≈ 2.3
Thus....our "equation" might be y = 2.3x + 20
This is closest to y = 2x + 20 ⇒ 2nd answer
I hope that makes sense, NSS...
