Which of these would be a correct technique while writing the Sans Serif B-point alphabet?

Maintaining even pressure is essential when writing in the Sans Serif B-point alphabet because it helps achieve consistent stroke widths and a clean, uniform appearance. This technique allows for smooth and steady lines that are characteristic of sans serif styles, where the focus is on simplicity and clarity without additional embellishments. Even pressure contributes to the overall professional look of the lettering, ensuring that each letter retains its intended shape and form.

In contrast, techniques such as incorporating shadows, keeping the pen point upright, and using a brush pen may not be suitable for this particular style of writing. Shadows and variations in angle or tool can alter the aesthetic of the Sans Serif alphabet, which is defined by its straightforward and unembellished design. Thus, focusing on even pressure is the most appropriate and effective technique for achieving a polished outcome in this specific calligraphic style.
