Correct answer and explanation

Correct answer: Lindlar catalyst

Explanation: ✅ Correct Answer: A) Lindlar catalyst 📚 Explanation: A Lindlar catalyst is used for the partial hydrogenation of alkynes to alkenes. It is specially designed to stop the reaction at the alkene stage, preventing it from turning into an alkane. This process typically produces 'cis' alkenes due to the way the hydrogen is added.
