Which of the following could be a slant cross section of a right cone? a) sphere. b) oval. c) triangle. d) circle.

Option; B is the correct answer.

                           B) Oval.

We know that when the slicing of a three dimensional figure is done by a plane we obtain a 2-dimensional figure.

Hence, option: A is discarded.

Also a circle is done when a slicing is done parallel to the base.

Hence, option: D is also discarded.

And an ellipse( which is also a oval shape figure) is obtained when the slicing is done slant.

                  Hence,the cross-section is oval.

its c or d   take a lucky guess my dude
