Which compound(s) out of the following is/are not aromatic?

•  Aromatic compounds are planar structure, cyclic, complete conjugated system (electron delocalisation) and follows Huckel rule (4n+2) n=0,1,2,3... 
• In compounds if there is odd no. of pi bonds then it is aromatic.
•  Anti-aromatic compounds have planar structure, cyclic, conjugation, does not follow huckel rule. It follows (4n) rule.
•  Cyclopropenyl cation follow (4n+2) rule: aromatic. 
• Cyclopentadienyl cation follow(4n) rule: anti-aromatic. 
• Cycloheptatrienyl anion follow (4n) rule: antiaromatic 
• Cycloheptatrienyl do not follow huckel rule : non-aromatic. 

Hence, the correct option is: (B) B,C and D.
