(A) The density of alkali metals generally increases down the group from $Li$ to $Cs$. However,there is an anomaly between $Na$ and $K$. The density of $K$ is slightly lower than that of $Na$ due to an abnormal increase in atomic volume in $K$. Thus,the correct order of density is $Li < K < Na < Rb < Cs$.
