**Concept: The question tests on solving a word problem**

**Solution:**

4 Large Cans = 6 Small Cans

1 Large Can = 1.5 Small Cans

4 sides of the house requires 24 small cans

So 1.5L + C = 24

Option 1: 1.5 * 2 + 24 = 27

Option 2: 1.5 * 4 + 18 = 6 + 18 = 24

Option 3: 1.5 * 6 + 16 = 9 + 16 = 25

Option 4: 1.5 * 8 + 8 = 12 + 8 = 20

Option 5: 1.5 * 12 + 12 = 18 + 12 = 30**Option B**
