i think because wen u react glucose with conc. h2so4, it leaves behind a charcoal residue. since glucose is also an aldehyde, i think the ans is (C).
but im not sure it might as well be (A). but its not (B) or(D).

Acetaldehyde polymerises in presence of few drops of conc. sulphuric acid, a vigerous reaction takes place and paraldehyde (CH3CHO)3 is formed.This is pleasent smelling liquid b.p.128 used in medicine as hypnotic.
