Consider the following four statement (i) - (iv) and select the correct option.
(i) SA node is natural pacemaker of heart
(ii) Human heart has inter-auricular foramen
(iii) Right atrioventricular valve is a semilunar value
(iv) Normal systolic and diastolic pressure of human is 120 and 60 mm Hg respectively.

Options

A. `{:("(i) (ii) (iii) (iv)"),("F F T F"):}`
B. `{:("(i) (ii) (iii) (iv)"),("F F T T"):}`
C. `{:("(i) (ii) (iii) (iv)"),("T T F T"):}`
D. `{:("(i) (ii) (iii) (iv)"),("T F F F"):}`

Explanation

To solve the question regarding the four statements about the human heart, we will analyze each statement one by one to determine their correctness.

### Step-by-Step Solution:

1. **Statement (i): SA node is the natural pacemaker of the heart.**
- The SA node (sinoatrial node) is indeed known as the natural pacemaker of the heart. It initiates the electrical impulses that trigger heartbeats. This statement is **True**.

2. **Statement (ii): Human heart has inter-auricular foramen.**
- The inter-auricular foramen (or foramen ovale) is present in the fetal heart, allowing blood to bypass the lungs. However, in a fully developed human heart after birth, this foramen closes and is no longer present. Since the statement does not specify that it refers to the fetal heart, we consider this statement **True** in the context of fetal development.

3. **Statement (iii): Right atrioventricular valve is a semilunar valve.**
- The right atrioventricular valve is known as the tricuspid valve, not a semilunar valve. Semilunar valves are located at the exits of the ventricles (pulmonary and aortic valves). Therefore, this statement is **False**.

4. **Statement (iv): Normal systolic and diastolic pressure of human is 120 and 60 mm Hg respectively.**
- The normal systolic blood pressure is typically around 120 mm Hg, but the normal diastolic pressure is about 80 mm Hg, not 60 mm Hg. Thus, this statement is **False**.

### Summary of Statements:
- (i) True
- (ii) True
- (iii) False
- (iv) False

### Conclusion:
The correct option based on the evaluation of the statements is that **statements (i) and (ii) are true, while statements (iii) and (iv) are false**.
