  2. Distributed methodology

  3. Air sniffing

A Correct answer
Explanation

Bluetooth prevents interference through Frequency-Hopping Spread Spectrum (FHSS). Devices hop 1600 times/second across 79 channels, so collisions are brief and retransmission handles them. L2CAP is a protocol layer above. 'Air sniffing' is not a Bluetooth term. Note: option has typo 'Hoping' instead of 'Hopping'.
