(B) Given equation: $\frac{a}{x + a + m} + \frac{b}{x + b + m} = 1$Multiplying both sides by $(x + a + m)(x + b + m)$,we get:$a(x + b + m) + b(x + a + m) = (x + a + m)(x + b + m)$$ax + ab + am + bx + ab + bm = x^2 + bx + mx + ax + ab + am + mx + bm + m^2$Simplifying the equation:$x^2 + 2mx + m^2 - ab = 0$For the roots to be equal in magnitude but opposite in sign,the sum of the roots must be $0$.Sum of roots $= -\frac{	ext{coefficient of } x}{	ext{coefficient of } x^2} = -\frac{2m}{1} = -2m$Setting $-2m = 0$,we get $m = 0$.

The value of $m$ for which the equation $\frac{a}{x + a + m} + \frac{b}{x + b + m} = 1$ has roots equal in magnitude but opposite in sign is
