Which list orders the following carbon–carbon bonds from longest to shortest: C≡C, C–C, C=C ? (a)

\mathrm{C}\equiv\mathrm{C} > \mathrm{C}=\mathrm{C} > \mathrm{C}-\mathrm{C}

(b)

\mathrm{C}=\mathrm{C} > \mathrm{C}-\mathrm{C} > \mathrm{C}\equiv\mathrm{C}

(c)

\mathrm{C}-\mathrm{C} > \mathrm{C}=\mathrm{C} > \mathrm{C}\equiv\mathrm{C}

(d)

\mathrm{C}-\mathrm{C} > \mathrm{C}\equiv\mathrm{C} > \mathrm{C}=\mathrm{C}
