# Which of the following is not true for transition metals.

$\begin{array}{1 1}(a)\;\text{They are malleable and ductile}\\(b)\;\text{They crystallize with body centred cubic and hexagonal close-packed structures only}\\(c)\;\text{They have high boiling and melting points}\\(d)\;\text{They show variable oxidation states although not always}\end{array}$

They crystallize with body centred cubic and hexagonal close-packed structures only
Hence (b) is the correct answer.
