The bandwidth of a $TCP$ connection is $1048560$ $bits/s$. Let $a$ be the value of $RTT$ in milliseconds, after which $TCP$ window scale option is required. Let $b$ be the maximum possible window size (with window scale option).
Then, the value of $a$ and $b$ are:
- $63$ and $65535 \times 2^{16}$
- $63$ and $65535 \times 2^{14}$
- $500$ and $65535 \times 2^{16}$
- $500$ and $65535 \times 2^{14}$
