Explanation:

Observe the numbers. They are not giving any meaning, but if combined in each code, all are divisible by 4. Like 48, 12, 76, 20, 64, 24 and so on.
Now observe the words that which letter of each word is taken and multiplied by 4 to give the code. So if we see first code. 76 will be 19*4, and 19 is for letter’s’. observe some more words if it is happening.
Observe that all the words have second letter vowel.
Now for symbols:
Take symbol which is present more. Lets take @
We see @ in first 3 codes at four places. Now see if any similarity in words which lead to 2 @ symbols in first code and one each in second and third code.
We see that there are two words in which second letter is ‘a’ in first code. One such word each in second and third codes.
Like this determine all the symbols
‘a’ – @
‘e’ – $
‘I’ – &
‘o’ – !
‘u’ – ^
Now for signs:
Observe ‘+’ sign – words from first two codes can be – easy, quality, piracy – all have letter ‘y’ at last
Find out for all signs
‘y’ – +
‘r’ – < ‘t’ – × ‘h’ – % ‘s’ – >
‘d’ – ≤
‘n’ – ≥
‘l’ – /

Hence, option 2 is the correct answer.
