Assertion (A): An unclocked flip-flop is called a latch.Reason (R): A ...
An unclocked flip-flop is called a latch, because the output of the flip-flop latches on to ‘1’ or ‘0' immediately after the input is applied. Hence, assertion is a correct statement. Reason is also a true statement but not the correct explanation of assertion.

Assertion (A): An unclocked flip-flop is called a latch.
Reason (R): A latch is constructed using two cross-coupled NAND gates or NOR gates.
Explanation:
A flip-flop is a digital circuit that can store one bit of information. It has two stable states, representing 0 and 1. A flip-flop can be either clocked or unclocked. A clocked flip-flop is synchronized to a clock signal and changes its state only on clock edges, while an unclocked flip-flop can change its state at any time.
Latches:
A latch is an unclocked flip-flop that can store and remember the state of its inputs. It can be constructed using two cross-coupled NAND gates or NOR gates, which form a feedback loop. The output of each gate is connected to one of the inputs of the other gate. This feedback allows the latch to remember its state even when the inputs change.
Assertion (A): An unclocked flip-flop is called a latch.
This statement is true. An unclocked flip-flop is indeed called a latch. Latches are used in digital circuits to store and remember data.
Reason (R): A latch is constructed using two cross-coupled NAND gates or NOR gates.
This statement is also true. Latches can be constructed using either NAND gates or NOR gates connected in a feedback loop.
Explanation of Reason:
Latches can be implemented using different logic gates, such as NAND gates or NOR gates. The basic latch circuit consists of two cross-coupled gates, where the output of each gate is connected to one of the inputs of the other gate. This feedback loop allows the latch to store and remember its state.
Conclusion:
Both the assertion and the reason are true. An unclocked flip-flop is indeed called a latch, and a latch can be constructed using two cross-coupled NAND gates or NOR gates. However, the reason does not provide a direct explanation for the assertion. The reason only states one way of implementing a latch, but it does not explain why an unclocked flip-flop is called a latch. Hence, option B is the correct answer.
