Correct option is B
In Boolean algebra, the
XOR (Exclusive OR) operation has the following properties:
1.
XOR Definition:
·
A ⊕
B = C means that the result of
A XOR B is
C.
· The XOR operation produces 1 if the number of 1s in the operands is odd; otherwise, it produces 0.
Now, the expression we are interested in is:
B ⊕
C.
Since
A ⊕
B = C, we can substitute C in terms of A and B:
B ⊕
(A ⊕
B).
We use the property of XOR:
B ⊕
(A ⊕
B) = A.
This is because XOR is
commutative and
associative, and we can think of it as undoing the XOR operation between B and A ⊕ B, thus returning the original A.
Important Key Points:
1.
XOR Inverse Property: XOR of a number with itself (e.g., A ⊕ A) results in 0. So, when we XOR B with A ⊕ B, the result is simply A.
2.
Commutative and Associative Properties: XOR operations satisfy both of these properties, allowing for flexible rearrangement of operands.
Knowledge Booster:
·
Option (a):
1 is incorrect because XOR does not simply result in 1 when applied to B and C.
·
Option (c):
A' is incorrect because the result is A, not the negation of A.
·
Option (d):
0 is incorrect because the result of XORing B and C is A, not 0.
