Options

A. The length of filaments in all stamens is the same
B. They have leaves without stipules but show parallel venation .
C. They have trilocular superior ovary with three ovules
D. They have fruits which are mostly berries and rarely capsule

Answer

To solve the question regarding the Liliaceae family, we need to analyze each statement provided and determine which one is true. Here’s a step-by-step breakdown:

### Step 1: Analyze the First Statement
- **Statement**: The length of filaments in all stamens is the same.
- **Evaluation**: This statement is false because in the Liliaceae family, the stamens can have unequal lengths.

**Hint**: Check if the stamens in the family have uniformity in length.

### Step 2: Analyze the Second Statement
- **Statement**: They have leaves without stipules but show parallel venation.
- **Evaluation**: This statement is true. Members of the Liliaceae family typically have leaves that do not have stipules and exhibit parallel venation.

**Hint**: Look for characteristics of leaves in the Liliaceae family, focusing on stipules and venation patterns.

### Step 3: Analyze the Third Statement
- **Statement**: They have a trilocular superior ovary with three ovules.
- **Evaluation**: This statement is false. While they do have a trilocular ovary, it typically contains only two ovules, not three.

**Hint**: Remember the structure of the ovary and the number of ovules in the Liliaceae family.

### Step 4: Analyze the Fourth Statement
- **Statement**: They have fruits which are mostly berries and rarely capsules.
- **Evaluation**: This statement is also false. The fruits of the Liliaceae family are primarily capsules, and berries are rare.

**Hint**: Consider the types of fruits produced by the plants in the Liliaceae family.

### Conclusion
After evaluating all the statements, the only true statement about the members of the Liliaceae family is that they have leaves without stipules but show parallel venation.

### Final Answer
The correct statement is: **They have leaves without stipules but show parallel venation.**
