Which of the following pairs of sets are disjoint(i) `{1, 2, 3, 4}`and {x : x is a natural number and `4 lt=xlt= 6`}(ii) `{a , e , i , o, u }`and `{ c , d , e , f}`(iii) {x : x is an even integer } and {x : x is an odd integer}

Explanation

To determine which of the given pairs of sets are disjoint, we need to check if they have any elements in common. Two sets are disjoint if their intersection is the empty set (denoted as ∅). Let's analyze each pair step by step.

### Step 1: Analyze the first pair of sets
**Sets:**
- Set A: `{1, 2, 3, 4}`
- Set B: `{x : x is a natural number and 4 ≤ x ≤ 6}`

**Finding elements of Set B:**
