$\huge\bold{\gray{\sf{Answer:}}}$

$\bold{Explanation:}$

First know what is compound ??

Compounds are those substances which are made up of two or more elements in a fixed ratio.

=>Compounds have their own chemical formulas.

Example : water which is a compound made of 2 molecules of oxygen and one molecule of hydrogen.$\bold{H_{2}O}$.

=>Salt which is a compund made of Sodium (NA) and chlorine (CL).=>NaCl ( one atom of sodium and one atom of chlorine)

=>Compounds are pure substance as it can't be broken down into simpler substance.As compounds is made of two molecular combination.If we talk about salt which is made of Na (sodium) and Cl (chlorine) in ratio of 1:1 it can be say that it's a pure substance because it contains 1 ratio of sodium only and 1 ratio of chlorine only.

From above all statement and properties of compounds.

$\bold{\odot(c)}$ It is mixed in any proportion by mass.

Correct form : It is mixed in fixed proportion.
