Which of the following statements is incorrect for sigma and $$\pi$$ - bonds formed between two carbon atoms?

ASigma - bond is stronger than a $$\pi$$- bond
BBond energies of sigma and $$\pi$$- bonds are of the order of 264 kJ/mol and 347 kJ/mol
Correct Answer
CFree rotation of surrounding atoms about a sigma-bond is allowed but not in case of a $$\pi$$- bond
DSigma- bond determines the direction between carbon atoms but a $$\pi$$- bond has no primary effect in this regard
