# Which statement is true about the transitional elements

$\begin{array}{1 1}(a)\;\text{They are highly reactive }\\(b)\;\text{They have low M.P.}\\(c)\;\text{They show variable oxidation states}\\(d)\;\text{They are highly electropositive}\end{array}$

They show variable oxidation state due to participation of ns and (n - 1)d electrons
Hence (c) is the correct answer.
