**Concept: The question tests on framing and solving Word Problems**

**Solution:**

We try to find p as a function of N = 48000 / N

When N = 48000, we get p = 48000 / 48000 = 1

When N = 12000, we get p = 48000 / 12000 = 4. Since p = $2, then this is p2p2

When N = 3000, we get p = 48000 / 3000 = 16. Since p = $4, then this is p2p2**Option B**
