In a digital communication system employing Frequency Shift Keying $\text{(FSK)}$, the $0$ and $1$ bit are represented by sine waves of $10 \; \mathrm{kHz}$ and $25 \; \mathrm{kHz}$ respectively. These waveforms will be orthogonal for a bit interval of

  1. $45 \; \mu \mathrm{sec}$
  2. $200 \; \mu \mathrm{sec}$
  3. $50 \; \mu \mathrm{sec}$
  4. $250 \; \mu \mathrm{sec}$
