I had been asked this question during an internship interview.

I need to ask this question from Pulmonary Function Analysers in division Pulmonary Function Analysers of Biomedical Instrumentation

Answer 1

Right option is (b) Toco-tonometer

The explanation is: The toco-transducers are location sensitive. They should be placed over the fundus where there is maximum motion with the contractions. The toco-tonometer transducer cannot be used in the same place as the foetal heart rate detector, thus the patient must have two transducers on her abdomen.
