Answer:
Inside the strong metal box, there is a microwave generator called a magnetron. When you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves. Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up.May 3, 2018
As we know that electric flux is given by


so in order to increase the flux we have two options
1. By increasing the area of the disc
2. by changing the orientation of disc so the area of the disc is parallel to the electric field
so correct answer will be
<em> A. increasing the area of the disk</em>
