Answer:
Option D.
Step-by-step explanation:
To find the answer we will analyse each options.
Option A.
If we rotate a semicircle by a vertical axis then an sphere will be formed. Therefore this option is not correct.
Option B.
In this rotation we will get a hollow sphere, so this option is also not correct.
Option C.
By rotation of a strip we will find the shape similar to the given object but there will not be a hole at the center. Therefore, the option is not correct.
Option D.
When we rotate this strip with a distance from vertical axis, we will find the same shape as given in the picture.
Option D is the correct option.
