The INCORRECT statement is:

Consider the following reactions:
'A' (C₇H₁₄) --(ozonolysis)--> 'B' + 'C'
'B' --(I₂ + NaOH)--> yellow ppt
'C' --(I₂ + NaOH)--> no yellow ppt
'C' --(Ag₂O/Δ)--> silver mirror
'C' --(LiAlH₄)--> 'D' --(Anhydrous ZnCl₂ & Conc. HCl)--> gives white turbidity within 5 minutes
'A' is:
