318223 Which of the following will show aromatic character?

318215 Statement A :
The compound cyclooctatetraene has the following structural formula.

It is cyclic and conjugated $8\pi$- electron system but it is not an aromatic compound.
Statement B :
$\left(\text{4n + 2}\right)\pi \text{ - }$ electron rule does not hold good and ring is not planar.

318216 Assertion :
[10]-Annulene is not aromatic though it contains Huckel number of n-electrons.
Reason :
Steric interaction between internal hydrogens makes it non-planar.

318217 Assertion :
Cyclopentadienyl anion is much more stable than allyl anion.
Reason :
Cyclopentadienyl anion is aromatic in character.
