Select the option that is true regarding the following two statements labeled Assertion (A) and Reason (R). Assertion (A): Whenever we measure an electrical signal, there are chances of over current which leads to overheating of the meter. In such cases, the meter can be protected by using a semiconductor diode of suitable rating. Reason (R): As soon as the diode is short-circuited, the meter current is diverted through the diode. As a result, the meter is being protected from excess heating.

Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count there by reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.   Consider the following digital circuits. 1. Multiplexers 2. Read Only Memories 3. D-latch 4. Circuit as shown in figure below Which of these come under the class of combinational circuits?
