To answer this, consider how $\text{KMnO}_4$ reacts with different functional groups under the conditions given. The diagram depicts the structure of the naturally found molecule cholesterol. Cholesterol is then treated separately with cold, dilute acidified $\text{KMnO}_4$, and with hot, concentrated acidified $\text{KMnO}_4$. What change occurs in the number of chiral carbon atoms in the molecule in each reaction?
- A+1, 0
- B+1, $-1$
- C+2, 0
- D+2, $-1$
