Answer:
Although options are missing, I found them from another source. Among given options: Option C is right. The chocolate and the salt might both be solids, making a heterogeneous mixture
Step-by-step explanation:
A heterogeneous mixture is simply any mixture that is not uniform in composition. Chocolate is composed of cocoa solids, cocoa butter and some sugar, and at room temperature, it's in a solid form. Salt is also a solid at room temperature. Thus, mixture of salt and chocolate cannot make uniform composition at room temperature. Hence, both making a heterogeneous mixture.
