The recombination frequency between the genes a `` \, \& \,c `` is `` 5 \%, b \,\&\, c `` is `` 15 \%, b \,\&\, d `` is `` 9 \%, a \,\&\, b `` is `` 20 \%, c\, \&\, d `` is `` 24 \% `` and `` a \,\&\, d `` is `` 29 \% `` . What will be the sequence of these genes on a linear chromosome?

(A)a, c, b, d
(B)a, d, b, c
(C)d, b, a, c
(D)a, b, c, d
