Which gate is similar to the function of two parrallel switches ?

Ans should be [B] High, because O/p of AND gate is High only when the both i/p is high, so to pass one i/p another i/p must be high.

It should be LOW because we want to inhibit a signal.

Means to restrain a signal from passing it must be 0.

Yes its right that to inhibit the signal in AND gate we have at least one input low.

Ya, low because, AND gate means A*B and OR gate means A+B, So, to inhibit means to get low signal, one of the input must b low, it mean 0*1=0.......0*0=0......we will get low output signal.
