Correct Answer

Option A is the correct answer.

Detailed Explanation

Without the image, common exam questions show a 6-carbon chain with a double bond between C2 and C3, a chlorine on C3, and the higher priority groups (Cl and CH₂CH₃) on the same side, giving the Z configuration.

Hint

Number the chain to give the double bond the lowest numbers, then assign E/Z based on priority.
