Solution

The correct options are
A $C H_{3} C O C H_{3}$
C $H C H O$
D $C H_{3} C H O$
Calcium acetate on dry distillation gives Acetone.
Calcium formate on dry distillation gives Formaldehyde.
A mixture of calcium formate and calcium acetate on dry distillation gives Acetaldehyde.

$(H C O O)_{2} C a + (C H_{3} C O O)_{2} C a \to H C H O + C H_{3} C O C H_{3} + C H_{3} C H O$

Therefore, all three options A, B, C will be formed on a dry distillation of a mixture of calcium formate and calcium acetate.

Hence the correct options are $A$ , $B$ and $C$
