Options

A. cyclopentadiene has conjugated double bonds
B. cyclopentadiene has both `sp^(2)` and `sp^(3)` hybridized carbon atoms
C. cyclopentadiene is a strain -free cyclic system
D. cyclopentadienide ion, the conjugate base of cyclopentadiene, is an aromatic species and hence has higher stability
