Identify (A), (B) and (C) in the following reaction sequence.
`C_(5)H_(5)OHoverset((A))toC_(6)H_(6)overset ((B))toC_(6)H_(5)NO_(2)overset((C))to"Azobenzene"`
A. `(A) = NaOH+ CaO,( B)= conc. H_(2)SO_(4)+ conc. HNO_(3), 60-70^(@)C, (C) - "glucose" + NaOH`
B. `(A) = "Zn power", (B)= conc. H_(2)SO_(4) + conc. HNO_(3), 100^(@) C, (C) = NH_(4)Cl +Zn`
C. `(A) = Zn , (B) = conc. H_(2)SO_(4)+ conc. HNO_(3), 60 -70^(@)C, (C) = Zn+ NaOH`
D. `(A) = NaOH + CaO, (B) = conc. HNO_(3) + conc. H_(2) SO_(4), "Reflux" 24 hrs. (C)= CH_(3)OH+Na`
