A. The clear liquid is denser than the black liquid.
B. The clear liquid is less dense than the black liquid.
C. The mass of the clear liquid is greater than the black liquid after it separates.
D. The volume of the clear liquid is greater than the black liquid after it separates

Answer 1

A. The clear liquid is denser than the black liquid.

Reason: The rapid separation indicates the liquids are immiscible and form layers by density. The clear liquid must be the denser one (the lower layer), whereas you cannot deduce relative mass or volume from the separation alone.
