# The absolute pressure at a certain point in a lake is \( P_{abs} \). If the local atmospheric pressure is \( P_{atm} \), which expression represents the gauge pressure \( P_{gauge} \) at that point?

The absolute pressure at a certain point in a lake is \( P_{abs} \). If the local atmospheric pressure is \( P_{atm} \), which expression represents the gauge pressure \( P_{gauge} \) at that point?

- **A.** \[ P_{abs} + P_{atm} \]
- **B.** \[ P_{abs} – P_{atm} \]
- **C.** \[ \dfrac{P_{abs}}{P_{atm}} \]
- **D.** \[ P_{abs} \]
