1. Check List Phrase Codes

We analyze the given coded phrases to identify word-to-code mappings:

• "check list has been generated" is coded as "jo ke al si ha"
• "His idea has check" is coded as "of al fu ha"
• "number in check list" is coded as "ha ya go ke"
• "His number generated there" is coded as "ya si fu xo"

2. Number Generated Code Deduction

Comparing phrases helps deduce codes:

• Comparing phrase 1 & 2 reveals ${check, has} = {al, ha}$.
• Comparing phrase 1 & 3 reveals ${check, list} = {ke, ha}$.
• Comparing phrase 2 & 3 identifies $check = ha$.
• Based on $check = ha$:
  • $has = al$
  • $list = ke$
• Comparing phrase 2 & 4 identifies $His = fu$.
• Comparing phrase 3 & 4 identifies $number = ya$.
• Comparing phrase 1 & 4 identifies $generated = si$.
• From phrase 1 ("check list has been generated" -> "jo ke al si ha") and known codes ($check=ha$, $list=ke$, $has=al$, $generated=si$), the remaining word been maps to the remaining code jo. Thus, $been = jo$.

3. My Target Phrase Codes

The target phrase is "My number has been generated". We need codes for:

• My (unknown)
• number (code: ya)
• has (code: al)
• been (code: jo)
• generated (code: si)

The required set of codes is {$My$, ya, al, jo, si}.

4. Option Match for My Number

We examine the options for the code set {ya, al, jo, si} plus one unknown code for My.

• Option 1 ($si ne jo ke na$): Contains jo, si. Missing ya, al.
• Option 2 ($ya ne al ke si$): Contains ya, al, si. Missing jo.
• Option 3 ($jo si ya al ne$): Contains jo, si, ya, al. The additional code is ne. This matches the required codes if $My = ne$.
• Option 4 ($ne fu ya ke al$): Contains ya, al. Missing jo, si.

Option 3 successfully represents the target phrase with the deduced codes.
