**Question:** Which reagent is missing for the reaction shown?

**Diagram Explanation:**
- The left side of the diagram shows a molecule with a benzene ring and a terminal alkyne (triple bond) with a methyl group (CH₃).
- The right side of the diagram shows the product with a benzene ring and an alkene (double bond) with two hydrogen atoms (H) and a methyl group (CH₃).

**Answer Choices:**
- a. \( \text{H}_2\text{SO}_4, \text{H}_2\text{O} \)
- b. \( \text{H}_2 \), Lindlar's catalyst
- c. \( \text{Na, NH}_3 \)
- d. \( \text{H}_2, \text{Pt/C} \)

Please select the correct reagent option that would result in the given transformation from an alkyne to a cis-alkene.
