Combinational Logic circuits:
The Combinational Logic circuits are circuits for which the present output depends only on the present input.
There is no memory element to store the past output.
It performs an operation that can be specified logically by a set of Boolean functions.
A combinational circuit can have ‘n’ number of inputs and 'm' number of outputs as shown:
Hence, All the above statements are correct.
Sequential Circuits: The block diagram shown below explains this:
The memory elements used are flip flops or latches.

Explanation:
Input Combination at that time:
In a combinational circuit, the output depends solely on the input combination at that specific time. This means that the output is determined by the current inputs provided to the circuit and not influenced by any previous inputs or outputs.
Characteristics of Combinational Circuits:
- Combinational circuits do not have any form of memory elements, so the output is purely a function of the current input combination.
- The output of a combinational circuit changes immediately when there is a change in the input combination.
- They are often implemented using logic gates to process the input variables and produce the desired output based on the given logic function.
Example:
A simple example of a combinational circuit is an adder. When two binary numbers are input to the adder, the sum is generated based on the current input combination (i.e., the binary digits being added at that moment).
Conclusion:
In conclusion, a combinational circuit is designed to produce output based only on the input combination present at that particular time. This distinguishes it from sequential circuits where the output is influenced by both the current input combination and the previous outputs.
