C. `{:("(p)","(q)","(r)","(s)"),("Higher temperature","Cool",CaSO_(4).H_(2)O,CaSO_(4)):}`
D. `{:("(p)","(q)","(r)","(s)"),("Higher pressure","Heat at 393 K",CaSO_(4),CaSO_(3)):}`

Answer

1

Explanation

`CaCl_(2)+H_(2)SO_(4)underset(-HCl)overset("Crystallisation")rarrCaSO_(4).2H_(2)O overset(393K)rarr2CaSO_(4).H_(2)O overset(gt393K)rarrCaSO_(4)`
