B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To determine whether the statement "FeO is basic in character" and the reason "Oxides of transition metals are basic when the metal is in lower oxidation state" are correct, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Nature of FeO**:
- FeO is an oxide of iron where iron is in the +2 oxidation state (Fe^2+).
- Basic character in metal oxides is often determined by the oxidation state of the metal.

2. **Reactivity of FeO**:
- To confirm that FeO is basic, we can look at its reaction with acids.
- For example, when FeO reacts with hydrochloric acid (HCl), it forms iron(II) chloride (FeCl2) and water:
\[ \text{FeO} + 2\text{HCl} \rightarrow \text{FeCl}_2 + \text{H}_2\text{O} \]
- This reaction indicates that FeO can neutralize an acid, which is a characteristic of basic substances.

3. **Analyzing the Reason**:
- The reason states that oxides of transition metals are basic when the metal is in a lower oxidation state.
- This is generally true; lower oxidation states tend to exhibit more basic properties, while higher oxidation states tend to be more acidic.

4. **Examples of Transition Metal Oxides**:
- Consider manganese oxides: MnO (Mn^2+) is basic, while MnO2 (Mn^4+) is amphoteric, and Mn2O7 (Mn^7+) is acidic.
- This trend supports the claim that lower oxidation states correlate with basic character.

5. **Conclusion**:
- Since FeO is basic and the reason provided is accurate, both the statement and the reason are correct.

### Final Answer:
Both the statement "FeO is basic in character" and the reason "Oxides of transition metals are basic when the metal is in lower oxidation state" are correct.
