x is radius of larger circle.
Area of larger circle = \({\pi} x^2\)

x is diameter of smaller circle = radius = \(\frac{x}{2}\)
Area of smaller circle = \({\pi} (\frac{x}{2})^2\) = \(\frac{{\pi} x^2}{4}\)

Area of the shaded region is = Area of Larger Circle - Area of Smaller Circle
\({\pi} x^2\) - \(\frac{{\pi}x^2}{4}\) = \(\frac{4{\pi}x^2 - {\pi}x^2}{4}\) = \(\frac{3}{4}{\pi}x^2\)
Answer A...
