Read the following statements and find the suitable option :-
(a) Generally petals are green, leaf like and protect the flower in the bud stage.
(b) Generally sepals are brightly coloured to attract insects for pollination.
(c) If stamens in a flower remain free (no cohesion) this is called polyandrous.
(d) Each ovary bears one or more ovules attached to a flattened, cushion like placenta.

Options

A. a, b and d are true but c and are false
B. c, d and are true but a and b are false
C. c and d are true but a, b and are false
D. d is true but a, b and c are false

Answer

To solve the question, we need to analyze each statement provided and determine whether they are true or false.

### Step-by-Step Solution:

1. **Analyze Statement (a)**:
- Statement (a) claims that "Generally petals are green, leaf-like and protect the flower in the bud stage."
- **Truth Evaluation**: This statement is false. Petals are typically brightly colored and serve to attract pollinators, while sepals are the green, leaf-like structures that protect the flower in the bud stage.

2. **Analyze Statement (b)**:
- Statement (b) states that "Generally sepals are brightly colored to attract insects for pollination."
- **Truth Evaluation**: This statement is also false. Sepals are usually green and not brightly colored; it is the petals that are colorful and attract pollinators.

3. **Analyze Statement (c)**:
- Statement (c) says, "If stamens in a flower remain free (no cohesion) this is called polyandrous."
- **Truth Evaluation**: This statement is true. When stamens are free and not fused together, the flower is described as polyandrous.

4. **Analyze Statement (d)**:
- Statement (d) states, "Each ovary bears one or more ovules attached to a flattened, cushion-like placenta."
- **Truth Evaluation**: This statement is true. The ovules are indeed attached to a structure called the placenta within the ovary.

### Conclusion:
- **True Statements**: C and D
- **False Statements**: A and B

Based on this analysis, the suitable option that reflects the true statements is option number 3.
