Final answer:
The correct answer for the question from the given options is option B.The expression (x+yˉ)z is equivalent to x+yˉ+z.
Step-by-step explanation:
The expression (x+yˉ)z is equivalent to option b. x+yˉ+z.
To simplify the expression, you can distribute the z to both terms inside the parentheses: z * (x+yˉ). This gives you zx+zyˉ, which is the same as x+yˉ+z. Therefore, the expression is equivalent to option b.
