Benzene's extraordinary stability is related to

Options

A. the presence of alternate single and double bond
B. the planar hexagonal structure
C. an extended `pi` system in which the electrons are symmetrical delocalised over all six carbon atoms
D. its symmetrical structure

Explanation

To understand why benzene exhibits extraordinary stability, we can analyze the structure and bonding of benzene step by step.

### Step-by-Step Solution:

1. **Identify the Structure of Benzene**:
- Benzene is a cyclic hydrocarbon with the formula C₆H₆. It consists of six carbon atoms arranged in a planar hexagonal ring, with each carbon atom bonded to one hydrogen atom.

2. **Hybridization of Carbon Atoms**:
