B could be any of , , , , , ,,,,,,,,,, or .

In general, a set with elements has subsets.

You can't define C until you have defined B.

Regardless, if C is indeed a subset of B, then C is a subset of A given that B is a subset of A.

In general if and then

Given set A= {m,n,o,p}
A. Find a subset B of A

        B = {m,o,p}

B. Find a subset C of B

        C = {m,p} 

C. Is C a subset of A?

       yes

D. Is there a general rule of this?

Yes, the transitive property of subset.  A subset of a subset of a given set is
a subset of the given set.  In symbols, if A ⊆ B  and B ⊆ C, then A ⊆ C.
