Question
![The question asks which of the following statements are true:
(i) \( R = \{ a + b \sqrt{3} \mid a, b \in \mathbb{Z} \} \).
Then \( (R, +, \cdot) \) is an integral domain.
(ii) \( R = \{ a + b \sqrt{\pi} \mid a, b \in \mathbb{Z} \} \).
Then \( (R, +, \cdot) \) is an integral domain.
(iii) \( R = \{ a + b \sqrt{3} \mid a, b \in \mathbb{Q} \} \).
Then \( (R, +, \cdot) \) is a field.
(iv) \( R = \{ a + b \sqrt{3} \mid a, b \in \mathbb{Z} \} \).
Then \( (R, +, \cdot) \) is a field.
