In a study to measure BP, two students Rakesh and Arif conduct a study on a dog. Rakesh measures BP using a mercury sphygmomanometer on the right femoral artery and Arif measures using a pressure transducer and pulse tracing on the left femoral artery. The mean arterial pressure for both Rakesh and Arif is the same i.e. 100 mmHg. After 5 minutes of injection of adrenaline, Rakesh measures blood pressure 130 mmHg and Arif as 120 mmHg. The difference of 10 mmHg is explained by

AFalsely high values at low pressure in pulse tracing
BFalsely low values at high pressure in pulse tracings
CFemoral artery is more sensitive to adrenaline on right side
DVentricular filling affects diastole period
