Answer:
I believe your answer would be y=1.
Step-by-step explanation:
The circle is located with its point on 1 of the x axis, and the cross section would be pulled straight from that term. So the cross section would need to be revolved around y = 1, instead.
This is just my best guess, so I hope it helps!
To get a sphere, we need to do a revolution around the line x = 1.
The line that we must use must be a line that divides the circle in two equal parts, so it must pass through its center.
We know that the center of our circle is the point (1, 0).
With that in mind, the two lines that we know that will divide the circle in two equal parts are:
(There are more lines, the above two are the simplest ones).
The only one that appears on the options is x = 1, so that is the correct option.
