(A) The correct matching is as follows:
$(1)$ General electronic configuration of $d$-block elements is $(n-1)d^{1-10}ns^{1-2}$,which corresponds to $(B)$.
$(2)$ $d$-block elements are also known as transition elements,which corresponds to $(A)$.
$(3)$ Groups $3$ to $12$ are defined by the fact that the last electron enters the $d$-orbital,which corresponds to $(D)$.
$(4)$ Lanthanoid elements range from atomic number $Z = 58$ to $71$,which corresponds to $(C)$.
Therefore,the correct sequence is $(1-B, 2-A, 3-D, 4-C)$.
