Best RF frequency for my application
The 2.4GHz frequency is more solid international standard than 433 MHz.
(source: http://en.wikipedia.org/wiki/ISM_band).
Any of the carrier frequencies mentioned could transmit to that distance.

Generally, lower frequencies have a better ability to pass through obstacles than the higher frequencies. But, it's almost always a question of the power of the signal.
If you don't have the power of the signal, you need to rely of the manufacturers data.
Note that generally the transceiver distances are line of sight distances i.e. no obstacles.
The obstacles can reduce that distance considerably.

I would recommend a 2.4GHz transceiver with at least double line of sight transecting distance that what you need.
TI are good, another option is the Nordic nRF24L01+ chip.
Note that it could also be possible with some Bluetooth modules but at that signal strength they are probably illegal!

Good luck,
