Dear Student,

◆ Answer - (B)

Elements groups 3 to 12 are called d-block elements.

◆ Extra information -

• Transition elements are elements having partially/completely filled d-orbital in their ground state.
• They are placed in d-block at middle of the periodic table between s-block and p-block.
• These are present in groups 3 to 12 of modern periodic table.
• All these are metals because of less no of electrons in last shell.

Thanks dear. Hope this helps you...
