Systolic pressure is higher than diastolic pressure because

Arrange and select the following events in the correct sequence during the measurement of blood pressure by a sphygmomanometer.
$i.$ Pulsatile sound disappears.
$ii.$ Cuff is inflated to block the brachial artery by external pressure.
$iii.$ First pulsatile sound is heard indicating systolic pressure.
$iv.$ Pressure in the cuff is slowly lowered.
$v.$ Cuff is wrapped tightly around the upper arm.

Given below are two statements.
Statement $I$ - Graphical recording of electrical variations detected at the surface of body during their propagation through the wall of heart is electrocardiograph.
Statement $II$ - The instrument used for the graphical recording of electrical variations detected at the surface of body during their propagation through wall of heart is electrocardiogram.
In the light of above statements,select the correct option given below:

The figure below shows a typical $ECG$ of a normal human. What does the $P$-wave represent?

Match List $I$ with List $II$.

List $I$	List $II$
$A$. $P$-wave	$I$. Beginning of systole
$B$. $Q$-wave	$II$. Repolarisation of ventricles
$C$. $QRS$ complex	$III$. Depolarisation of atria
$D$. $T$-wave	$IV$. Depolarisation of ventricles

Choose the correct answer from the options given below:
