1.	In an atomic solid with BCC arrangement of atoms, the atomic radius of the host atom is 270 pm. A guest atom of largest size is present at one of the faces without disturbing original unit cell dimensions. If Coordinates of the centre of this guest atom are (a/2, a/4, 0 ), where 'a' is the side length of unit cell, radius of the guest atom is closest to A) 180 pm B) 135 pm C) 78.57 pm D) 57.5 pm
