Answer:
Option b is correct that is a solid and a plane.
Step-by-step explanation:
The cross section means when two three dimensional intersects and gives the two dimensional figure.
Option a:
A solid and a line is not correct because line is not a three dimensional figure.
Option b:
A solid and a plane is correct because both of them are three dimensional figures for example:
If a plane cuts a sphere it will give circle which is a two dimensional figure.
Option c:
A plane and a plane when intersects gives a line which is not a two dimensional figure.
Hence, incorrect.
Option d:
A plane and line is not correct because line is not a three dimensional figure.
