# $CH_3,NH_2,OH$ and $F$ in increasing $pk_b$ values are :

$(a) \;CH_3 < NH_2 < OH < F \\ (b)\;F < OH < NH_2 < CH_3 \\ (c)\;OH < NH_2 < CH_3 < F \\ (d)\;none$

Lesser the electron negativity of donor atom, more is its tendency to give a pair of electrons, more is its basicity.
As basicity increases , value of $Pk_b$ decreases.
Hence a is the correct answer.
