A student investigates the rate at which dissolved ozone, \(\text{O}_3\text{(aq)}\), oxidizes a hypothetical dissolved contaminant, \(\text{P(aq)}\). The student obtains the following initial-rate data at constant temperature.

| Trial | \([\text{P}]\) (M) | \([\text{O}_3]\) (M) | Initial rate (M/s) |
|-------|---------------------|-------------------------|--------------------|
| 1     | 0.010               | 0.060                   | \(6.0 \times 10^{-5}\) |

Which of the following rate laws is consistent with the data?

- **A.** \(\text{rate}=k[\text{P}][\text{O}_3]\)
- **B.** \(\text{rate}=k[\text{P}][\text{O}_3]^2\)
- **C.** \(\text{rate}=k[\text{P}]^2[\text{O}_3]^2\)
- **D.** \(\text{rate}=k[\text{P}]^2[\text{O}_3]\)
