Since the outer circle has diameter 2, radius is 1 and area of the circle = \(π * 1^2 = π\) Similarly the inner circle has diameter 1, radius is 1/2 and area of the inner circle is \(π *(1/2)^{2} = π/4\) Hence, area of shaded region = area of outer circle  area of inner circle = 3/4 * π(Option A)

\(D = 2\) and \(d = 1\) So, \(R = 1\) and \(r = \frac{1}{2}\) Area of the shaded region is \(π(R^2  r^2)\) Or, Area of the shaded region is \(π(1  1/4)\) Or, Area of the shaded region is \(\frac{3π}{4}\) Hence, the correct answer must be (A)
