Read the given information carefully and answer the questions based on it: In a certain code language,

‘Several single port around’ is coded as ‘po xl yu vb’
‘Single event cost edition’ is coded as ‘rf zx vb wa’
‘Cost around public order’ is coded as ‘km po rf tf’
‘Public host winter edition’ is coded as ‘vc ur km zx’

‘zx’ is the code for ___.

The correct option is Edition.

To find the word coded as ‘zx’, we compare the sentences containing this code.

Let us write down the given statements and their corresponding codes:
Statement 1: ‘Several single port around’ ⇒ ‘po xl yu vb’
Statement 2: ‘Single event cost edition’ ⇒ ‘rf zx vb wa’
Statement 3: ‘Cost around public order’ ⇒ ‘km po rf tf’
Statement 4: ‘Public host winter edition’ ⇒ ‘vc ur km zx’

Notice that the code ‘zx’ appears in both Statement 2 and Statement 4:
- Codes in Statement 2: {rf, zx, vb, wa}
- Codes in Statement 4: {vc, ur, km, zx}
The only common code between these two statements is ‘zx’.

Now, let us find the common words between Statement 2 and Statement 4:
- Words in Statement 2: {Single, event, cost, edition}
- Words in Statement 4: {Public, host, winter, edition}
The only common word between these two statements is ‘edition’.

Since ‘zx’ is the only common code and ‘edition’ is the only common word, the code ‘zx’ must represent ‘edition’.
