Match the reactions given in Column-$I$ with the names given in Column-$II$.

(A) The correct matches are as follows:
$(i)$ The reaction of an aryl halide with an alkyl halide in the presence of sodium metal is known as the Wurtz-Fittig reaction. Thus,$(i)$ matches with $(b)$.
(ii) The reaction of two moles of aryl halide with sodium metal in the presence of dry ether to form diphenyl is known as the Fittig reaction. Thus,(ii) matches with $(a)$.
(iii) The reaction of a diazonium salt with $Cu_2X_2$ to form an aryl halide is known as the Sandmeyer reaction. Thus,(iii) matches with $(d)$.
(iv) The reaction of an alkyl chloride with sodium iodide in the presence of dry acetone is known as the Finkelstein reaction. Thus,(iv) matches with $(c)$.
Therefore,the correct sequence is $(i-b, ii-a, iii-d, iv-c)$.
