I seem to have seen this question before. Since, the question does not specifically tells whether all the vertices of the square are on the circle, answer should be E.

"inscribed" means that the square touches the circle on all four vertices.
Should be D then...

I would go with D too

'Inscribed' means all 4 vertices touching the circle, with its Diagnol = Diameter

What is the OA ?

Answer is D as inscribed means that vertices lie on the circle.
