Correct option is A)
Since, when A and B both are logic 1 then no current will flow through the both 50Ω resistors, because both the diodes will not conduct. therefore, whole current will flow through R=10K and output is potential difference across the R=10K which will be 6V in this case means high Now, When either of the input is low current through terminal which is low will flow through it and most of the current will flow through the 50Ω resistance since it is very very less than R=10K therefore, Potential across R=10K will be less than 1V . Hence, when either of input is low output is also low. When both the inputs are low same case as when either of input is low will be there hence output will also be low. Therefore, above circuit acts as a AND Logic gate.
