# If A is a subset of B (not necessarily proper) and B is a subset of C (not necessarily proper) the A is a proper subset of C

If A is a subset of B (not necessarily proper) and B is a subset of C (not necessarily proper) the A is a proper subset of C.

True or False
if false must provide a counterexample

A: {apple, orange, pineapple}
B: {apple, orange, pineapple}
C: {apple, orange, pineapple}

A⊆B ∧ B⊆C -> A⊂C

Is this true or false?
