Consider the table below showing the bit error rate (BER) of different modulation schemes versus the SNR. There is a user who transmitted a $100\mathrm{KB}$ file using TCP and a code rate of 1 . Remember that the BER is the fraction (ratio) of bits that are erroneous after demodulation at the receiver. If the SNR is 40 , and the sender $(Tx)$ and receiver $(Rx)$ were using QAM 256 modulation, how many less erroneous bits will the receiver detect when $\mathrm{Tx}$ and $\mathrm{Rx}$ switch to QAM 16? Select one: $\begin{array}{l}[42,000,43,000[\\ >=43,000\\ [40,000,41,000[\\ [41,000,42,000[\\ <40,000\end{array}$
