A TCP sender successfully establishes a connection with a TCP receiver and starts the transmission of segments. The TCP congestion control mechanism’s slow-start threshold is set to 10000 segments. Assume that the round-trip time is fixed at 1 millisecond. Assume that the sender always has data to send, the segments are numbered from 1, and no segment is lost. Let 𝑡 denote the time (in milliseconds) at which the transmission of segment number 2000 starts.

Which one of the following options is correct?

  1. A.

    9 ≤ 𝑡 < 10

  2. B.

    10 ≤ 𝑡 < 11

  3. C.

    11 ≤ 𝑡 < 12

  4. D.

    12 ≤ 𝑡 < 13
