'it' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'alternative inri fable with ordinary fellow' is the wordplay.
'alternative' is an anagram indicator.
'with' is an insertion indicator.
'ordinary' becomes 'O' (abbreviation e.g. O-Levels).
'fellow' becomes 'f' (abbreviation - of a society etc.).
'inri'+'fable'='inrifable'
'inrifable' is an anagram of 'lifebrian'.
'o'+'f'='of'
'lifebrian' going around 'of' is 'LIFE OF BRIAN'.

'in' acts as a link.
