In that 8-bit data is just entered it was not shifted to another register. So here there is no no. Of clock pulse. It was in the first clock cycle only, so it requires only one clock pulse. AND observe that in question it will be given that the data is entered not shifted when it can be shifted we can count the no. Of clock pulses. But here only the one clock pulse because it is in first cycle.
