MCQ
The output of a $2-$input $\text{OR}$ gate is zero only when its :
  • Both inputs are $0$.
  • B
    Either input is $1.$
  • C
    Both inputs are $1.$
  • D
    Either input is $0.$

Answer

Correct option: A.
Both inputs are $0$.
The truth table for $2-$input $\text{OR}$ gate is as shown in the figure. Thus, the output is zero only when both inputs are zero.
