Best answer
Correct option is (b) JSObject

Explanation: JSObject is the type of JavaScript objects in the JSAPI. When a JavaScript object is passed or returned to Java code, it is wrapped in an instance of JSObject. When a JSObject instance is passed to the JavaScript engine, it is unwrapped back to its original JavaScript object. The JSObject class provides a way to invoke JavaScript methods and examine JavaScript properties.
