Answer: Option(b) is correct
Explanation:
According to question, pain cry can start suddenly without any hint in infants if burping is not done. The appropriate way to capture Jane's cry is to take-in a large volume of air and hold it for short amount of time and then let go.This will relax and stop the crying.
Other options are incorrect because expulsion of small air volume due to crying, warm up crying and unstable whimper with pauses along with breathing are not the methods for controlling Jane's cry.Thus, the correct option is option(b).
