Explanation:

We know that 1 yard is equal to 3 feet.

3 yards = 3 x 3 = 9 feet

So, 3 yards is equal to **9 feet**. So, write the letter B in front of 3 yards.

We know that 1 yard is equal to 36 inches.

2 yards = 2 x 36 = 72 inches

So, 72 inches is equal to **2 yards**. So, write the letter C in front of 72 inches.

We know that 1 feet is equal to 12 inches.

3 feet = 3 x 12 =** 36 inches**

So, 3 feet is equal to 36 inches. So, write the letter A in front of 3 feet.
