Answer

Explanation:

Step1: Recall ionic - compound properties

Ionic compounds have high melting and boiling points, dissolve in water, and conduct electricity in solution or molten state.

Step2: Analyze compound A

Compound A has high melting and boiling points, dissolves in water, and conducts electricity. These are typical ionic - compound properties.

Step3: Analyze compound B

Compound B has low melting and boiling points and only poorly conducts electricity, which are not typical ionic - compound properties.

Step4: Analyze compound C

Compound C does not conduct electricity and has low melting and boiling points, which are not typical ionic - compound properties.

Step5: Analyze compound D

Compound D has high melting and boiling points, dissolves in water, and conducts electricity. These are typical ionic - compound properties.

Answer:

compounds D and A
