Hint: Adrenaline is manufactured in the medulla of the adrenal gland. The all-around effect of adrenaline is to formulate the body for the fight or flight reaction in times of stress, i.e., for vigorous abrupt action.

Complete Answer:
Progesterone enables the blastocyst for implanting as well as developing along with it protects against the deportation of the developing pregnancy. Progesterone decreases towards the time of delivery, leaving oestrogen to improve the uterine contractility.

Option – A – Increase blood Supply in Skeletal Muscle – Vasodilation of the arterial tree outcomes in raised blood flow, that holds up more oxygen to the tissues per unit time. In addition to this the enhanced blood flow increases micro vessel hematocrit, that also supports increased oxygen birth to the active muscles

Option – B – Hyperglycemia – Hyperglycemia is the technical word used to describe for high blood glucose or blood sugar. High blood sugar occurs when the body has too fragile insulin or when the body can't use insulin properly.

Option – C – Uterine Relaxation – Uterine relaxation permits simpler fatal manipulation as well as lessens the probability of initiation of labour from uterine surgical manipulation. Uterine relaxation may enable increased uterine blood flow as long as maternal blood distress is retained, and it results in fatal disclosure to some volatile anaesthetic agents.

Option – D – Tachycardia – Tachycardia is the medical word used for a heart rate over 100 beats per minute. There are many heart rhythm illnesses such as arrhythmias which can result in tachycardia. Sometimes, it is considered normal for a person to have a fast heartbeat.

So, the accurate answer to the question is option C “Uterine Relaxation”.

Note: Key activities of adrenaline encompass increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, as well as enlarging the pupil in the eye, redistributing blood to the muscles along with altering the body's metabolism, so as to maximise blood glucose levels.
