Explanation:

Let’s break down what’s given:

- B is taller than only C.

? So C is the shortest, then B.

- A has less height than F, who is less than E.

? So, E > F > A.

- Only two people are in between D and A.

? The order could be: D _ _ A or A _ _ D.

- The person with the third lowest height is 140 cm tall.

? Hold onto this; we’ll use it to check the rank.

- E is 20 cm taller than A.

? E is definitely above A.

Let’s try to put them in order from shortest to tallest:

1. C (shortest)

2. B (next)

3. Who could be third? Options are A, F, D.

4. We know that E > F > A.

5. Arrange D and A with two people between them.

Possible order: C < B < A < F < D < E (let’s try to fit)

But A < F < E and D has to be two spots away from A.

Try: C < B < A < F < D < E

Here, D is two positions above A.

Now, E is at the top.

Let’s check options:

- 1. E

- 2. F

- 3. A

- 4. D

- 5. C

The tallest is E.

Here’s why:

- E is definitely taller than everyone else.

- D isn’t above E in the height chain.

- Every clue points to E being the tallest.

So the correct answer is:

Option 1: E
