A)Log2(1+4)times as fast
B)Log2(1+1/4)times as fast
C)about 4 times as fast
D)at the same speed, but more reliably

According to the Shannon Equation, the channel capacity is proportional to the bandwidth and the signal-to-noise ratio. If we quadruple the bandwidth while keeping the signal-to-noise ratio constant, the channel capacity will also quadruple. Therefore, we can transmit about 4 times as much data as before.
