'from choice' is the definition.
I can't tell whether this defines the answer.

'ring to get a point sorted out' is the wordplay.
'ring' becomes 'o' (letter resembling a ring).
'to get' means one lot of letters goes inside another.
'sorted out' indicates anagramming the letters.
'point' anagrammed gives 'optin'.
'o' placed into 'optin' is 'OPTION'.
