Group displacement law states that the emission of \[\alpha \] or \[\beta \] particles results in the daughter element occupying a position, in the periodic table, either to the left or right of that of the parent element. Which one of the following alternatives gives the correct position of the daughter element

A)  On emission of \[\alpha \] particles -2 groups to the right           On emission of \[\beta \] particles-1 group to the right

B)  On emission of \[\alpha \] particles -2 groups to the right           On emission of \[\beta \] particles-1 group to the left

C)  On emission of \[\alpha \] particles -    2 groups to the left         On emission of \[\beta \] particles-1 group to the left

D)  On emission of \[\alpha \] particles -2 groups to the left             On emission of \[\beta \] particles-1 group to the right
