Answer:

<h2>A) 1 inch drawing, 3 feet actual.</h2>

Step-by-step explanation:

The given scale is

$\frac{1}{4}in=1ft$

That is, each foot equals one quarter of an inch. In other words, 1 inch equlas 4 feet, because

$\frac{1}{4}in=1ft\\ 1in=4ft$

That means, 1 inch drawing represents 4 feet actual. Now, let's see which choice doesn't have this same proportion.

You can observe that option A has a proportion where 1 inch drawing equals 3 feet actual, which is not the same proportion as the given, because the given one is 1 inch drawing equals 4 feet actual.

Therefore, the right answer is A.
