    For large scale integration we require a logic gate having high packing density as well as low power dissipation. MOS logic gate have both the two qualities that's why MOS logic gate is preferred for large scale integration.

    Correct Option: A

    A major drawback in the ECL logic is that a very low value of resistors is required, which result in a constant current in the storage cell. This constant current causes relatively higher power dissipation compared to the TTL or CMOS or DCTL logic gate family.

    CMOS logic consumes very less power dissipation because there is zero static power dissipation means power dissipation will occur only when P-MOS i.e., pull-up transistor is ON. However, CMOS is slowest among the given logic family because of the high input impedance (i.e., due to SiO2) takes more time for charging and discharging.

    Correct Option: C
