Best answer
The correct answer is (a) low

Best explanation: Fractional Bandwidth is the ratio of the frequency range of antenna to the center frequency. If Fractional bandwidth is high, then Bandwidth of the antenna is also more. So the quality factor decreases as it is inversely proportional to the bandwidth.
