Assertion : Angular frequency of `LC` oscillations is `2 rad//s` and maximum current in the circuit is `1 A`. Then, maximum rate of change of current should be `2 A//s`.
Reason: `((dI)/(dt))_(max)=(I_(max))omega`

Options

A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
C. If Assertion is true, but the Reason is false.
D. If Assertion is false but the Reason is true.

Explanation

To solve the given problem, we need to analyze the assertion and the reason provided.

**Assertion:** The angular frequency of LC oscillations is \(2 \, \text{rad/s}\) and the maximum current in the circuit is \(1 \, \text{A}\). Then, the maximum rate of change of current should be \(2 \, \text{A/s}\).

**Reason:** The maximum rate of change of current is given by the formula:

\[ \left( \frac{dI}{dt} \right)_{\text{max}} = I_{\text{max}} \cdot \omega \]

### Step-by-Step Solution:

1. **Identify the given values:**
- Angular frequency (\(\omega\)) = \(2 \, \text{rad/s}\)
- Maximum current (\(I_{\text{max}}\)) = \(1 \, \text{A}\)

2. **Use the formula for the maximum rate of change of current:**
According to the reason provided, we can use the formula:
\[ \left( \frac{dI}{dt} \right)_{\text{max}} = I_{\text{max}} \cdot \omega \]

3. **Substitute the known values into the formula:**
\[ \left( \frac{dI}{dt} \right)_{\text{max}} = 1 \, \text{A} \cdot 2 \, \text{rad/s} \]

4. **Calculate the maximum rate of change of current:**
\[ \left( \frac{dI}{dt} \right)_{\text{max}} = 2 \, \text{A/s} \]

5. **Conclusion:**
The assertion that the maximum rate of change of current should be \(2 \, \text{A/s}\) is indeed correct based on the given values and the formula provided.

### Final Answer:
- The assertion is true, and the reason is a correct explanation of the assertion.
