The correct answer is A. 270.833 Kbps.
Bluetooth is a wireless technology that allows two or more devices to communicate with each other over a short distance. It is used in a variety of devices, including smartphones, laptops, and speakers.
The channel symbol rate in Bluetooth is the number of symbols that can be transmitted per second. The symbol rate is determined by the modulation scheme used in Bluetooth, which is Gaussian Frequency-Shift Keying (GFSK). GFSK is a modulation scheme that uses two frequencies to represent the two binary values, 0 and 1. The symbol rate for GFSK is given by the following equation:
$R_s = \frac{2f_c}{B}$
where $f_c$ is the carrier frequency and $B$ is the bandwidth.
The carrier frequency for Bluetooth is 2.4 GHz and the bandwidth is 795 kHz. Therefore, the symbol rate for Bluetooth is:
$R_s = \frac{2(2.4 \times 10^9 \text{ Hz})}{795 \times 10^3 \text{ Hz}} = 270.833 \text{ Kbps}$
This means that in each second, 270.833 symbols can be transmitted over a Bluetooth link.
The other options are incorrect because they do not represent the actual symbol rate for Bluetooth.
