   Answer: (3) Both 1 and 2

   उत्तर: (3) 1 और 2 दोनों

   A great circle is formed by a plane passing through the centre of a sphere, so it is the largest circle that can be drawn on its surface. Because its plane passes through the centre, every great circle (the Equator, or any meridian together with its opposite meridian) divides the Earth into two equal hemispheres.
