Within the Krebs cycle, one step that releases energy for the human body is the conversion of fumaric acid to malic acid. $\text{HO}_2\text{CCH=CHCO}_2\text{H} \rightarrow \text{HO}_2\text{CCH(OH)CH}_2\text{CO}_2\text{H}$ Which reagent(s) would carry out this conversion in the laboratory?
- Aacidified $\text{KMnO}_4$(aq)
- B$\text{Br}_2$(aq) followed by hot $\text{NaOH}$(aq)
- C$\text{H}_2\text{O}$(l) with Pt catalyst
- D$\text{H}_2\text{O}$(g) with $\text{H}_2\text{SO}_4$
