24. Why is the operating frequency for CMOS devices critical for determining power dissipation?

(a) At low frequencies, power dissipation increases.
(b) At high frequencies, the gate will only be able to deliver 70.7 % of rated power.
(c) At high frequencies, charging and discharging the gate capacitance will draw a heavy current from the power supply and thus increase power dissipation.
(d) At high frequencies, the gate will only be able to deliver 70.7 % of rated power and charging and discharging the gate capacitance will draw a heavy current from the power supply and thus increase power dissipation.
