Explanation:

Let’s look at the order in the dictionary for the given words:

- Ecology

- Enormous

- Electric

- Exterior

- Ecliptic

Dictionary order is based on first, then second, then subsequent letters:

- “Ecology” (E-c...)

- “Ecliptic” (E-c-l...)

- “Electric” (E-l...)

- “Enormous” (E-n...)

- “Exterior” (E-x...)

So, the correct order is:

1. Ecology (1)

2. Ecliptic (5)

3. Electric (3)

4. Enormous (2)

5. Exterior (4)

Now examining your option:

- Option 1: 1, 5, 3, 2, 4 (matches!)

- Option 2: 5, 1, 3, 2, 4 (starts with 5, doesn’t match)

- Option 3: 1, 5, 4, 3, 2 (order is wrong)

- Option 4: 1, 5, 2, 3, 4 (order is wrong)

Correct Answer:

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

Summary of all statements/options:

- Option 1: Correct alphabetical order.

- Option 2: Starts wrongly with 5.

- Option 3 and 4: Incorrect sequence per dictionary order.

- Always arrange by comparing letters from left to right.
