Answer:
d. psychogenic shock
Explanation:
Psychogenic shock causes the dilatation of the blood vessels supplying the muscles. This then leads to a decrease in blood pressure and this decrease alters the flow of blood that supplies the brain and ultimately leading to fainting or syncope. Although the pulse rate increases but this only acts as a compensatory mechanism due to the fall in blood pressure. The skin also becomes cold and sweaty as a result of the decrease blood flow.
