Which of the following is false about Emulators? a. Can receive or dial phone calls from real world cellular network b. Useful to distribute and sell device application c. Environment for debugging and testing code d. Provides a look and feel of physical device within PC environment Select the most appropriate sequence below -

Mobile device emulators run on PCs and provide a simulated environment for testing mobile applications. Statement (a) is FALSE because emulators cannot make or receive real cellular network calls - they simulate the device environment, not the network connection. Statement (b) is also FALSE because emulators are development/testing tools, not distribution platforms for selling applications. Since the question asks which statement is 'false' and groups a & b together, option A (a & b above) is correct because both statements are indeed false.
