Answer:
The correct answer is option C-ANP (Atrial natriuretic peptide).
Explanation:
Vasoconstriction is the narrowing of the blood vessels which can stop or block the blood flow.
Vasoconstriction reduces the urine formation during stress conditions through the action of hormones like ADH (anti-diuretic hormone), norepinephrine, epinephrine and angiotensin II produced via the sympathetic nervous system.
The atrial natriuretic hormone (ANP) is a cardiac hormone produced to lower the blood pressure or reduce blood plasma through vasodilation, increased vascular permeability and increase renal excretion.
Thus, option C is the correct answer.

The CPT code for second trimester obstetrical ultrasound with a fetal anatomical evaluation to obtain fetal heartbeat and fetus’s position is CPT code 76811.
Explanation:
According to the Society for Maternal-Fetal Medicine, the CPT code 76811 ultrasound is a pregnant uterus real-time ultrasound complete with image documentation performed to diagnose fetal anomalies. It is done during the second trimester of pregnancy with various indications like twin, triplet, or quadruplet pregnancy; suspected fetal any genetic or anatomic anomalies; maternal gestational diabetes, obesity etc. Fetal anatomical structures like abdomen, chest (heart), extremities, head, face and neck, spine, and position of the fetus are examined under this ultrasound. This ultrasound provides fetal 4-chamber heart view with heart activities to identify any fetal or congenital heart defects
