Frames of 20000Bytes are sent over a 10Megabytes per second duplex link between two hosts.Propagation time is 45ms(One-way). Suppose that the sliding window protocol is used with the sender window size of 16 and acknowledgements are always piggybacked.After sending 35 frames, what is the minimum time the sender will have to wait before starting transmission of next frame?

Decidability
Consider the following language over $\sum=\{0,1\}$ $L=\{<M>|$ M is a turing machine that accepts all strings of length atmost 5 $\}$ Since, this is a non-trivial property of TM, so surely it is undecidable. Now, Applying Rice’s Theorem part 2, $T_{yes}=\{0,1\}$ and $T_{no}=\sum^*$ and $T_{yes} \subset T_{no}$ so this is NOT RE. Have I correctly applied property 2?

Time complexity
What is the worst case time complexity to count pairs of numbers with difference ‘k’ from an input array of ‘n’ numbers O(log n) O(n log n) O(n)^2 O(n^2 log n) The answer given was B but since worst case time is stated shouldn't the answer be C? I mean we can check all possible pairs in the worst case. Correct me if I am wrong?
