Explanation:
A DIAC (Diode for Alternating Current) is a two-terminal semiconductor device that conducts current when the voltage across it reaches its breakover voltage. It is commonly used in applications such as triggering thyristors or triacs.

Two Terminals:
The DIAC has two terminals, which are the anode and the cathode. These terminals are used to connect the DIAC in a circuit.

Anode:
The anode is the positive terminal of the DIAC. It is typically denoted by the symbol 'A'. The anode is connected to the positive side of the circuit.

Cathode:
The cathode is the negative terminal of the DIAC. It is typically denoted by the symbol 'K'. The cathode is connected to the negative side of the circuit.

False:
The correct answer to the question is option 'B', which states that the given statement is false. This means that the DIAC does not have two terminals, anode and cathode.

Explanation:
The DIAC actually has three terminals, which are the anode, the cathode, and the gate. The gate is the third terminal of the DIAC and is denoted by the symbol 'G'. It is used to control the triggering of the DIAC.

Conclusion:
In summary, the given statement is false. A DIAC has three terminals, namely the anode, the cathode, and the gate. The anode and the cathode are used to connect the DIAC in a circuit, while the gate is used to control its triggering.
