Answer 2

Answer:

please mark me as brainiest

Step-by-step explanation:

Let A is a subset of B and B is a subset of C.

Then there is an x in B such that, for every x in B,x is in C and there exists an x in A such that, for every x in A,x is in B. Thus, for every x in A,x is also in C, and thus A is a subset of C.

Hence proved.
