An isolated thermodynamic system executes a process. Choose the correct statement(s) from following
A. No heat is transferred
B. No work is done
C. No mass flows across the boundary of the system
D. No chemical reaction takes place within the system

For an isolated system, there is no flow of mass as well as energy across the system boundary hence options A, B, and C are correct.
An example of an isolated system is a perfectly insulated thermos flask.
