# Which of the following represent the correct order of increase in covalent character?

$\begin{array}{1 1}(a)\;CaCl_2 < CaF_2 < CaBr_2 < CaI_2\\(b)\; CaCl_2 < CaF_2 < CaI_2 < CaBr_2\\(c)\; CaI_2 < CaBr_2 < CaCl_2 < CaF_2\\(d)\; CaF_2 < CaCl_2 < CaBr_2 < CaI_2\end{array}$

As the size of the anion increases, the polarisability of anion increases
Hence (d) is the correct answer.
