The correct answer is letter A

Sinoatrial node (SA) or pacemaker or sino-atrial node: special region of the heart, which controls the heart rate. It is located near the junction between the right atrium and the superior vena cava and consists of a cluster of specialized muscle cells. The rhythmic frequency of these muscle fibers is approximately 72 contractions per minute, while the atrial muscle contracts about 60 times per minute and the ventricular muscle, about 20 times per minute. Due to the fact that the sinoatrial node has a faster rhythmic frequency in relation to the other parts of the heart, the impulses originating from it spread to the atria and ventricles, stimulating these areas so quickly, so that the rhythm of the SA node becomes the rhythm of the whole heart; that's why it's called a pacemaker.

Alex777 [14]

- How can photos be used as alternate forms of argument?

It can be used as a visual proof to convince others about your point.

Argument often derived from personal conviction.  This personal conviction often really hard to get rid off even if the oppositions provides a clear and logical argument to debunk it.

Visual proof often harder to deny since it can depict a certain situation in a more convincing way rather than personal recollection . Often times, this can be a lot stronger compared to trying to convince others simply by using words.

-  Can a photo convince you to take a specific action or to think a certain way?

Absolutely.

For example,  Let's say that you hear 2 people arguing in the court. Person A accused person B for killing person C at December 12th. Person B denied the accusation.

At this point, you probably not really sure who's in the right.

But, let's say that<u> person B showed a photo that proved he is actually in another city</u> on December 12th and it is impossible for him to be at the crime scene on the time of person C attack.

That photo could easily win the argument in person B's favor and convince others who witness it that he is telling the truth.
