If A= {x : x is a natural number}, B = {x : x is an even natural number}C = {x : x is an odd natural number} and D = {x : x is a prime number }, find(i) `A nnB` (ii) `A nnC` (iii) `A nnD`(iv) `B nnC` (v) `B nnD` (vi) `C nnD`

Explanation

To solve the problem step by step, we will find the intersections of the sets A, B, C, and D as defined in the question.

### Given Sets:
- **A** = {x : x is a natural number} = {1, 2, 3, 4, 5, ...}
- **B** = {x : x is an even natural number} = {2, 4, 6, 8, ...}
- **C** = {x : x is an odd natural number} = {1, 3, 5, 7, ...}
- **D** = {x : x is a prime number} = {2, 3, 5, 7, 11, ...}
