Answer:
A. These fonts have tapered corners and edges at the end of their strokes.
Step-by-step explanation:
The main characteristic that distinguishes a serif font and a sans serif font is the fact that serif fonts have "serifs" in their letters. A serif is a decorative line or taper that is added at the beginning or at the end of a letter's stem. This creates small horizontal and vertical planes within a word. On the other hand, sans serif fonts lack these decorative elements.
