Taking on and choosing to follow the promotion (8)

I believe the answer is:

adopting

'taking on' is the definition.
('adopt' can be a synonym of 'take on')

'choosing to follow the promotion' is the wordplay.
'choosing' becomes 'opting' (I've seen this before).
'to follow' is a charade indicator (letters next to each other).
'the promotion' becomes 'ad' (short for advert).
'opting' put after 'ad' is 'ADOPTING'.

'and' acts as a link.

(Another definition for adopting that I've seen is " Taking on (another's child)".)

I've seen this clue in the Sydney Morning Herald.
