Are all of the following constructions correct ?
1) And now meet the lady in whom I place absolute trust.
2) And now meet the lady whom/who/that I place absolute trust in.
3) And now meet the lady I place absolute trust in.
Thank you in advance,
In 2, the use of 'whom' with the preposition at the end sounds unnatural to me. Though technically correct, it is not commonly used- people who use 'whom' tend to follow the first pattern.
