The more commonly used baking powder contains about $30 \% NaHCO_3$,$20 \% NaAl(SO_4)_2$,$10 \% Ca(H_2PO_4)_2$ and $40 \% \text{starch}$. Which of the following statements is/are correct?
- A$Ca(H_2PO_4)_2$ is acidic and when moistened it reacts with $NaHCO_3$ evolving $CO_2$ gas
- B$NaAl(SO_4)_2$ slows down the decomposition reaction of $NaHCO_3$ so that $CO_2$ is evolved more slowly
- C$NaAl(SO_4)_2$ is acidic and when moistened it reacts with $NaHCO_3$ evolving $CO_2$
- DBoth $(A)$ and $(C)$
