Correct Answer

Option B

Detailed Explanation

The IUPAC name "5–Methoxy–3–Nitro cyclohexene" accurately describes a compound with a methoxy group (–OCH₃) at the 5th position and a nitro group (–NO₂) at the 3rd position of a cyclohexene ring, which is a six-membered carbon ring with one double bond. Other options are not applicable as they do not provide valid IUPAC names or structures that correspond to the compound described. Understanding the IUPAC naming conventions helps in identifying the position and nature of substituents on cyclic compounds, which is crucial for accurate chemical communication.
