The problem presented is asking to find the fraction of the area of the larger circle that is shaded.

First, let's break down the geometry of the figure. The image shows a large circle with four smaller circles inside it. The four smaller circles appear to be tangent to each other and to the large circle, and they form a pattern that divides the area of the large circle.

To solve the problem, follow these steps:

1. Determine the area of the larger circle:

   • Let the radius of the larger circle be $R$.
   • The area of the larger circle is $\pi R^2$.

2. Determine the radius of the smaller circles:

   • If the radius of each smaller circle is $r$, then the diameter of each smaller circle is $2r$.
   • The centers of the four smaller circles form a square inscribed in the larger circle. The side length of this square is $2r$, and the diagonal of this square is equal to the diameter of the larger circle.
   • Using the Pythagorean theorem: $(2r\sqrt{2}) = 2R$. Thus, $r = R/\sqrt{2}$.

3. Calculate the area of the smaller circles:

   • The area of one smaller circle is $\pi r^2$.
   • Substituting $r = R/\sqrt{2}$, the area of one smaller circle is $\pi (R/\sqrt{2})^2 = \pi (R^2/2)$.

4. Calculate the total area of the four smaller circles:

   • The total area of the four smaller circles is $4 \times \pi (R^2/2) = 2\pi R^2$.

5. Determine the shaded area:

   • The shaded area is the area of the larger circle minus the area of the four smaller circles.
   • Shaded area $= \pi R^2 - 2\pi R^2 = \pi R^2 (1 - 2) = \pi R^2 \times (-1) = -\pi R^2$.
   • There seems to be a mistake here. Let's re-calculate the proper area subtraction.
   • The correct shaded area should be: $\pi R^2 - 2 \times \pi (R^2/2) = \pi R^2 - \pi R^2 = 0$.

There is clearly an error in our calculations. Let's reconsider the geometric setup:

Given that the four smaller circles perfectly fill the large circle, the correct fraction of the shaded area should be:

• Fraction of the area of the large circle covered by the smaller circles $= 2 \times (\pi (R^2/2)) / (\pi R^2) = 1$.
• The fraction of the larger circle that is not shaded (which is what we seek) is the inverse of the area fraction covered by the smaller circles.

So, the corrected understanding gives:

The actual unshaded fraction is zero, as the smaller circles cover the area completely, so there is no shading.

This calculation appears simpler and is incorrect due to misinterpretation of the geometric setup.

The correct shaded fraction calculation should involve recognizing that:

1. Shaded area fraction = Total Area - Area covered by circles / Total Area.

Thus, let's look back to answer options:

• $(A)\ \frac{1}{4}$
• $(B)\ \frac{1}{2}$
• $(C)\ \frac{1}{3}$
• $(D)\ \frac{1}{6}$

From visual inspection, the correct choice is $\frac{1}{6}$ as shaded regions.
