Right option is (a) Sagittal
The explanation: The plane that cuts the body in equal right and left parts are called the sagittal section. The right and the left parts of the plane are called the para sagittal planes/sections of the body. If the body is cut in such a way that the superior and inferior parts are seen, it is a horizontal cut. If the body is sliced in such a way that the anterior and posterior parts are seen, then its the coronal plane.
