The relay satellite transmits the TV programme continuously from one part of the world to another because its
(a) period is greater than the period of rotation of the earth
(b) period is less than the period of rotation of the earth about its axis
(c) period has no relation with the period of the earth about its axis
(d) period is equal to the period of rotation of the earth about its axis
