Best answer
Right choice is (b) 1.3

The best I can explain: The stomach produces acid to destroy any harmful substances and microbes that may enter the body through food. It also produces pepsin which starts the digestion of proteins. Pepsin requires an acidic medium to work. When the stomach is full, the acidity may fall to pH 4.
