Almost all silicon devices $($integrated circuits$)$ implement some sort of 'clock tree' along with various pre$-$scaling inserted.$$ Which of the following statements is not true about the use of these structures?

Group of answer choices

Clock trees allow different blocks to be clocked at different rates

Pre$-$scalers help make a high$-$speed clock be usable at lower frequencies.

Clock trees can help minimize skew throughout the chip

Pre$-$scalers are inserted because the downstream hardware can't run as fast as the clock.
