Explanation: The total bandwidth of an FM phone transmission is determined by Carson's Rule, which estimates the approximate bandwidth needed to transmit an FM signal. Carson's Rule states that the bandwidth (BW) is equal to two times the sum of the maximum frequency deviation ($\Delta$f) and the maximum modulating frequency (f$_m$). Using the given values: Maximum frequency deviation ($\Delta$f) = 5 kHz Maximum modulating frequency (f$_m$) = 3 kHz Applying Carson's Rule: BW = 2 * ($\Delta$f + f$_m$) BW = 2 * (5 kHz + 3 kHz) BW = 2 * (8 kHz) BW = 16 kHz Therefore, the total bandwidth is 16 kHz. Options A, B, and C are incorrect as they do not apply Carson's Rule correctly; 3 kHz is the modulating frequency, 5 kHz is the deviation, and 8 kHz is only half of the calculated bandwidth.
