A. All except (b) & (d)
B. (b) , (c) & (d)
C. (d) only
D. (b) & (d)

Answer

To determine the incorrect statements regarding parthenocarpic fruits, let's analyze each of the provided statements step by step.

### Step 1: Analyze Statement (a)
**Statement (a):** Ovary grows into a fruit without fertilization.
- **Explanation:** This statement is true. Parthenocarpic fruits develop from the ovary without the need for fertilization, meaning that the ovary can mature into a fruit even if fertilization does not occur.

### Step 2: Analyze Statement (b)
**Statement (b):** They are always formed from polycarpellary and apocarpous ovary.
- **Explanation:** This statement is incorrect. Parthenocarpic fruits can arise from various types of ovaries, not just polycarpellary and apocarpous. They can also develop from syncarpous ovaries, so the use of "always" makes this statement false.

### Step 3: Analyze Statement (c)
**Statement (c):** They are seedless.
- **Explanation:** This statement is true. Since parthenocarpic fruits develop without fertilization, there is no formation of zygotes, and consequently, no seeds are produced.

### Step 4: Analyze Statement (d)
**Statement (d):** Are always true fruits.
- **Explanation:** This statement is incorrect. True fruits are typically formed from fertilized ovaries. Since parthenocarpic fruits develop without fertilization, they do not qualify as true fruits. Therefore, this statement is false.

### Step 5: Analyze Statement (e)
**Statement (e):** Banana and grapes are parthenocarpic fruits.
- **Explanation:** This statement is true. Both bananas and grapes are known to be parthenocarpic, as they develop without seeds.

### Conclusion
Based on the analysis:
- The incorrect statements are **(b)** and **(d)**.

### Final Answer
The incorrect options are **B** and **D**.
