Explanation:

Let’s first list the words and look at their spellings to see the dictionary order:

- Cable

- Cachet

- Canary

- Cancel

- Candid

The correct dictionary order is:

1. Cable

2. Cachet

3. Canary

4. Cancel

5. Candid

Here’s why:

- After ‘Ca’, ‘b’ (Cable) comes first, then ‘c’ (Cachet), then ‘n’ (Canary), ‘n’ (Cancel), and finally ‘n’ (Candid).

- Among Canary, Cancel, Candid, the next deciding letter is ‘a’.

- Canary comes before Cancel (Canary vs Cancel: ‘a’ vs ‘c’), then Cancel before Candid (Cancel vs Candid: ‘e’ vs ‘i’).

Let’s look at the options:

- Option 1: 1, 4, 2, 1, 3, 5 ? This repeats numbers, doesn’t make sense.

- Option 2: 4, 3, 5, 2, 1 ? Cable, Cachet, Canary, Cancel, Candid.

- Option 3: 3, 4, 3, 2, 1, 5 ? Repeats numbers, incorrect order.

- Option 4: 4, 3, 5, 4, 1, 2 ? Repeats numbers, incorrect order.

Correct answer:

Option 2: 4, 3, 5, 2, 1
