'self-determination' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'work on it somehow' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'somehow' is an anagram indicator.

'onit' is an anagram of 'tion'.
'op'+'tion'='OPTION'

'to' acts as a link.

(Other definitions for option that I've seen before include "Choice of portion" , "Preference" , "Right to choose" , "Altenative choice" , "Something that may be chosen" .)

I've seen this clue in The Globe and Mail.
