A. Placentation in Primrose is basal
B. Flower is a modified shoot
C. Tomato fruit is capsule
D. Orchid seeds have oil rich endosperm.

Answer

To solve the question "Which is correct?" regarding the statements about flowers and their characteristics, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- The first statement claims that "placentation in primrose is basal."
- This statement is **incorrect** because primrose exhibits **free central placentation**, not basal placentation.

2. **Analyze the Second Statement:**
- The second statement asserts that "flower is a modified shoot."
- This statement is **correct**. Flowers are indeed modified shoots that have evolved to perform reproductive functions.

3. **Analyze the Third Statement:**
- The third statement states that "tomato fruit is a capsule."
- This statement is **incorrect** because a capsule is a type of fruit that is usually dry and dehiscent. Tomatoes are classified as berries, not capsules.

4. **Analyze the Fourth Statement:**
- The fourth statement claims that "orchid seeds have oil-rich endosperm."
- This statement is **incorrect** because orchid seeds actually **lack endosperm** altogether.

### Conclusion:
After analyzing all four statements, the only correct statement is the second one: "flower is a modified shoot." Thus, the correct answer is **B**.
