A solid sphere of radius R is placed on smooth
horizontal surface. A horizontal force 'F' is
applied at height 'h' from the lowest point. For
the maximum, acceleration of centre of mass,
which is correct : -
 (1) h = R
 (2) h = 2R
 (3) h = 0
 (4) No relation between h and R

According to me answer should be 1...but in book answer is 4..

-- No relation between h and R

Because smooth surface is given so rolling motion is not possible. Sphere will perform linear motion.
