Step 1: Understanding the Nib Shape.
The line in the image is drawn with a nib that has a slanted angle. When a circle is drawn with the same nib, the nib will create an elliptical shape due to its slant.
Step 2: Analyzing the Options.
- Option (a): This shape does not correspond to the expected result of the nib's angle.
- Option (b): This shows the correct elliptical shape created by the nib at an angle.
- Option (c): This option also does not match the expected result.
- Option (d): Similarly, this does not fit the expected elliptical shape.
Step 3: Conclusion.
Thus, the correct answer is (b) B, as it shows the proper result of drawing a circle with a slanted nib.

\boxed{\text{The correct answer is (b) B.}}
