**QUESTION 2**

**Which statement is true about the following reaction? (Lone pair electrons have been omitted.)**

The diagram shows a chemical reaction where a cyclic six-membered carbon ring with an iodine (I) substituent reacts with a cyanide ion (C≡N⁻), resulting in the substitution of the iodine atom with the cyanide group, forming a six-membered ring with a nitrile group.

**Options:**

- ○ "CN is a leaving group."

- ○ A curved reaction arrow would start from the C in "CN."

- ○ A curved reaction arrow would start from the I.

- ○ "I⁻ is the nucleophile."
