Answer 1

Answer: (B)

transition elements

The elements in groups 1B through 8B (also known as 3 through 12) are called the transition metals. They are called d block elements because the electrons being added in this block of elements are being added to the d orbital. They are placed between metals and non-metals i.e. in center in periodic table.
