is "to" used?.. (amendment of previous question)

[SARDORBEK]

He was used to … because he was a good story-teller and used to make up tales about animals.

a) being listened to
(b) being listened


Dear ALAN,
I meant "being listened" in the second version. And now
1) Which version is correct?
2) And could YOU please explain why?..

Thank you..

[Alan]

(a).

The particle in a passivized phrasal VP must always be retained. Cf. e.g.

He was used to being looked at.


I do not like being spoken to in that way.
