Which characteristic is true about the letters of the Sans Serif B-point alphabet?

The correct point about the letters of the Sans Serif B-point alphabet is that they have the same thickness. This characteristic is fundamental to sans serif typefaces, which are known for their clean, modern appearance. Unlike serif fonts that often feature varying line widths and decorative elements, sans serif fonts maintain a uniform stroke weight. This gives the letters a sleek and straightforward look, making them particularly legible and easy to read, especially in digital formats.

The uniformity in thickness helps in conveying a sense of clarity and modernity, which is often sought after in contemporary design. This is why many designers and typographers choose sans serif fonts for a wide range of applications, from signage to digital interfaces.
