Each compound shown below is reacted on its own with excess $\text{NaBH}_4$. The resulting product from each reaction is then heated with excess concentrated $\text{H}_2\text{SO}_4$. For each case, one or more products are produced with molecular formula $\text{C}_7\text{H}_{10}$. Which compounds produce only a single final product with molecular formula $\text{C}_7\text{H}_{10}$?
- A1, 2 and 3
- B1 and 2 only
- C2 and 3 only
- D1 only
