Answer:
Therefore, given that input A is true and the input B is false, then the resulting value of the output will be 'False'.
Hence, option B is true.
Explanation:
Given
input A = T
input B = F
OR GATE:
INPUTS OUTPUT
A B C
T F T
It means when the inputs of the OR GATE is 'T' and 'F' respectively, the output would be 'T'.
Then if we implement NOT gate on the output 'T', the final output will be 'F'.
Because the NOT gate would just convert the 'T' into 'F'.
Therefore, given that input A is true and the input B is false, then the resulting value of the output will be 'False'.
Hence, option B is true.
