‘nee muk pic’ means ‘grave and concern.’
⇒ We can infer that ‘pic’ represents ‘concern.’
‘ill dic so’ means ‘every body else.’
⇒ We can infer that ‘ill’ represents ‘every.’
Now, to find the code for ‘every concern,’ we need the words for "every" and "concern."
‘ill’ represents ‘every.’
‘pic’ represents ‘concern.’
Therefore, the code for ‘every concern’ should be ‘ill pic.’
Since ‘ill pic’ is not one of the options, so, the correct answer is (D): Cannot be determined.
