Which of the following is (are) correct statements?
i. `0.1 M CaCl_(2)` has higher boiling point than `0.1 M NaCl`.
ii. `0.05 M Al_(2)(SO_(4))_(3)` has higher freezing point than `0.1 M K_(3)[Fe(CN)_(6)]`.
iii.`0.1 M` glucose exerts higher osmotic pressure than `0.08 M CH_(3)COOH` (25% dissociated). iv. Vapour pressure of `0.05 M` urea solution is greater than that of `0.05 M KCl` solution.
a.i,ii ,b.ii,iv , c. i,ii,iii , d. i,ii,iv

Explanation

To solve the question, we need to analyze each statement one by one based on the principles of colligative properties of solutions. Let's go through each statement step by step.

### Step 1: Analyze Statement i
**Statement:** `0.1 M CaCl₂` has a higher boiling point than `0.1 M NaCl`.

**Explanation:**
- CaCl₂ dissociates into 3 ions: 1 Ca²⁺ and 2 Cl⁻ ions.
- NaCl dissociates into 2 ions: 1 Na⁺ and 1 Cl⁻ ion.
