Explain the right answer

Suppose that there is no other traffic in the network to worry about. If we have a packet of 10Kbits that is at the head of the queue for router A at time =0, where will the first bit of the packet be at the time equal to the transmission delay? Assume that the propagation speed is 2105m/s. routerArouterB x Waiting for the remaining bits to arrive to router B. Not enough information to say. Still propagating on the link on its way to router B. Just reaching router B
