The right answer is Electrocardiography (or Electrocardiogram).
In a typical plot, one can notice five characteristic waves. They are called P, Q, R, S and T. The illustration below shows what a normal electrocardiogram looks like:
* the P wave marks the depolarization during the contraction of the atria;
* the PR interval indicates the time required to transmit the electrical impulse of the sinus node of the atria to the ventricular muscles;
* the QRS complex marks depolarization and ventricular contraction;
* the QT interval corresponds to the global ventricular repolarization;
* T wave refers to the end of ventricular repolarization.
A friend should have their own opinion and not just say whatever to please you so A is crossed out. C is crossed out because a good friend should display honesty whenever they have something to say wether it is good or bad so that way you can trust them. D is also crossed out because a friend should be reliable all the time wether they are angry with you or not. So that leaves option B. Option B is correct because a friend should care about your feelings and not just say mean things and harm you emotionally. So that means the correct answer is
B) Empathizes by showing care and sensitivity to your feelings.
