A text font fits 12 characters per inch. Using the same font, how many characters can be expected per yard of text? There are 12 inches in a foot, and 3 feet in a yard.

A yard contains 3 × 12 = 36 inches. At 12 characters per inch, the text fits 12 × 36 = 432 characters per yard. Therefore, the correct choice is D, 432 characters.
