Question

What shape could be rotated about the y-axis as shown below to form a square pyramid?

A) Sphere
B) Cone
C) Cylinder
D) None of the above

Answer 1

The answer is D.) none of the above because there is no shape 

Answer 2

Option: D is the correct answer.

D) None of the above.

Explanation:

Clearly from the figure attached to the question we could see that there is no shape given. Hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

Since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

Hence, the correct answer is:

D) None of the above.
