The correct answer is: C - I bond in iodoform is weak and $\mathrm{C}-\mathrm{Cl}$ bond in chloroform is strong
On heating $\mathrm{C}-\mathrm{I}$ bond in $\mathrm{CHI}_3$ breaks, but $\mathrm{C}-\mathrm{Cl}$ bond in $\mathrm{CHCl}_3$ does not break. Thus, $\mathrm{AgNO}_3$ gives precipitate AgI with iodoform.
