Answer: C. A researcher may claim that one variable causes another to occur if test results are significant.
Explanation:
Correlation analysis is not meant to show causation between variables but merely to find out if there is a relationship.
While there is a chance of one variable causing another if they are correlated, it is not always the case as there might be another unforeseen variable.
Even if results are significant, a researcher should never claim that one variable can cause another from correlation analysis.

Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.
