(a) Amount of memory used
(b) Amount of memory unused
(c) Amount of memory used & unused
(d) Amount of memory required
Correct answer is (a) Amount of memory used
To explain I would say: usedJsHeapSize returns an object of type ObjectObject. An object created with MemoryInfo constructor, containing jsHeapSizeLimit, totalJSHeapSize and usedJSHeapSize properties with numerical values. The usedJsHeapSize property is the amount of memory that all of the current objects in the heap are using.
