Option B is the correct answer because the passage describes that traditional methods of cooking food at home will help one remain fit and lead an active life. Thus, option B is the right answer.
Option A is incorrect because the passage mentions that long term consumption of junk food will affect the metabolism. Thus, option A is not the right answer.
Option C is incorrect because the passage describes that over consumption of packaged and processed foods will have adverse effects on kidneys. So option C is not the right answer.
Option D is incorrect because the passage describes that packaged and processed foods use artificial chemicals whereas natural food is available in plenty in our country so one should use them. So option D is not the right answer. It is not stating its advantage, but simply its origin.
