Option A and C are correct.

Step-by-step explanation:

We are given Scale of drawing a room is $\frac{1}{4}\,inch=1\,ft$

Option A).

1 inch = 3 ft.

from given relation,

$3\,ft=3\times\frac{1}{4}=\frac{3}{4}\,inch$

So, this does not represent a Proportional relationship.

Option B).

2 inch = 8 ft.

from given relation,

$8\,ft=8\times\frac{1}{4}=2\,inch$

So, this represent a Proportional relationship.

Option C).

$\frac{1}{2}\,inch=2\,ft.$

from given relation,

So, this does not represent a Proportional relationship.

Option D).

$1\frac{1}{2}\,inch=6\,ft.$

from given relation,

$6\,ft=6\times\frac{1}{4}=\frac{3}{2}=1\frac{1}{2}\,inch$

So, this represent a Proportional relationship.

Therefore, Option A and C are correct.
