Correct option is C
The Ex-OR (Exclusive OR) gate is commonly used as a parity checker. A parity checker ensures that the total number of 1's in a binary sequence is either odd (odd parity) or even (even parity).
· The Ex-OR gate outputs 1 if an odd number of inputs are 1 and outputs 0 if an even number of inputs are 1.
· This property makes it ideal for detecting errors in parity bits during data transmission.
