Overriding == without hashCode

A Product class overrides `operator ==` to compare ids but does not override `hashCode`. Two products with the same id are added to a Set. What is likely?

A.The Set throws a runtime error because hashCode is missingB.The Set always keeps only one product, since == is checked firstC.The Set may keep both, because equal objects have different hash codesD.The analyzer refuses to compile the Set literal with these objects
