By the second law of thermodynamics:
Heat can not spontaneously flow from cold regions to hot regions without external work being performed on a system.
Heat transfer is the passage of thermal energy from a hot ( t B = 80° C ) to a colder body ( t A = 40° C ).
Answer: B ) Heat flows from object B to object A.

Option B is right that is Heat flows from object <span>B </span>to object because if 2 bodies have different temperature so heat always transfer from higher to lower ,from hot to cold .
