Let’s decode the information step by step:

- "6218" = Laptop is a computer

- "8217" = Computer is a machine

- Matching words (is, computer) must have the same code in both: "is" and "computer" codes overlap.

- Both "is" and "computer" appear in both, so 8 and 2 must be for "is" and "computer" (order unknown).

- New words: "Laptop" =6 or 1; "machine"=7 or 1.

- So, none of the codes 3, 4, 5, 7, 8, 9 in answer options have been mapped yet.

Now, looking at the answer options for "Machine makes our life easy":

- All words new ("makes", "our", "life", "easy", "machine"). None mapped distinctly from codes so far.

- Must check which option uses only new digits, none of 6, 2, 1, 8, 7.

- Only Option 2: 75894 and Option 3: 58795 use all new digits; Option 1 has 4’s which are never mapped.

So, correct answer is:

Option: 2, 75894

- Codes are all unassigned in the previous mapping, so this matches best.
