Concept:CMOS is a logic family that consumes very little power because it draws current mainly during switching.
Explanation:The main advantage of CMOS is its extremely low power consumption.
It uses complementary pairs of transistors, so one transistor is always off in steady state.
Therefore, almost no current flows when the circuit is idle.
Power is dissipated only during the brief moment of switching.
This is why CMOS is preferred in battery-operated and portable devices.
Other logic families like TTL and ECL consume more power than CMOS.
Options like high power rating, small signal operation, and switching capability are not the primary advantage of CMOS.
Hence, low power consumption is the correct choice.
Answer:Option D – Low power consumption.
