11. An AND gate will function as OR if :
(a) All the inputs to the gates are “1”
(b) All the inputs are ‘0’
(c) Either of the inputs is “1”
(d) All the inputs and outputs are complemented
12. NAND gates are preferred over others because these :
(a) Have lower fabrication area
(b) Can be used to make any gate
(c) Consume least electronic power
(d) Provide maximum density in a chip
13. In case of OR gate, no matter what the number of inputs.
(a) A 1 at any input causes the output to be at logic 1
(b) A 1 at any input causes the output to be at logic 0
(c) A 0 at any input causes the output to be at logic 0
(d) A 0 at any input causes the output to be at logic 1
