Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about a compound leaf that appears simple due to the suppression of 1-2 lateral leaflets. We need to identify which plant this characteristic is associated with among the given options.

2. **Identifying Leaf Types**:
- **Simple Leaves**: These have a single blade.
- **Compound Leaves**: These consist of multiple leaflets arranged on a single petiole.

3. **Types of Compound Leaves**:
- Compound leaves can be classified into various types: unifoliate (1 leaflet), bifoliate (2 leaflets), trifoliate (3 leaflets), quadrifoliate (4 leaflets), and multifoliate (more than 4 leaflets).

4. **Analyzing the Options**:
- **Option 1: Hardwickea**: This is a genus of flowering plants but does not typically have the characteristic described.
- **Option 2: Parkinsonia**: Known for its compound leaves but does not fit the description of appearing simple due to suppressed leaflets.
- **Option 3: Citrus**: This plant is known to have unifoliate leaves that appear simple but are actually compound due to the suppression of 1-2 lateral leaflets.
- **Option 4: Coriandrum**: This plant has simple leaves and does not fit the description.

5. **Conclusion**: Based on the analysis, the correct answer is **Option 3: Citrus**. The leaves of Citrus appear simple because they are unifoliate, with suppressed lateral leaflets.
