Best answer
Right choice is (d) Cr

Explanation: Of all the 3d transition elements, chromium has the highest melting point. More the number of unpaired electrons in the d-block element, stronger is the metallic bond formation. Since chromium contains more number of unpaired electrons, it has the highest melting point.
