Which of the following statements is not correct regarding oviparous animals ?

Options

A. Females lay fertillised/unfertilised eggs at a safe place.
B. Development of zygote takes place outside the female's body.
C. Examples of oviparous animals are all birds, most reptiles and egg-laying mammals.
D. None of these

Answer

To determine which statement is not correct regarding oviparous animals, we need to analyze the characteristics of oviparous animals and the options provided. Here’s a step-by-step solution:

### Step 1: Understand Oviparous Animals
Oviparous animals are those that lay eggs. The development of the embryo occurs outside the mother's body. This is a key characteristic that distinguishes them from viviparous animals, which give birth to live young.

**Hint:** Remember that oviparous means "egg-laying" and involves external development.

### Step 2: Recognize Fertilization Types
Oviparous animals can undergo both internal and external fertilization. Internal fertilization occurs when the sperm fertilizes the egg inside the female's body, while external fertilization occurs outside, typically in water.

**Hint:** Think about how different species reproduce and where fertilization occurs.

### Step 3: Hatching Environment
The hatching of eggs in oviparous animals typically occurs in the external environment. This means that the eggs are laid in a safe place where they can develop and eventually hatch.

**Hint:** Consider where you might find eggs in nature and how they develop.

### Step 4: Evaluate the Options
Now, let’s analyze the options provided in the question (though they are not explicitly listed here, we can infer based on the context):

1. Females lay fertilized and unfertilized eggs at a safe place.
2. Development of zygote takes place outside the female body.
3. Examples of oviparous animals include fishes, amphibians, birds, and some reptiles.
4. None of these statements are incorrect.

### Step 5: Identify the Incorrect Statement
Based on the analysis:
- The first statement is correct as females do lay both fertilized and unfertilized eggs.
- The second statement is correct since the development of the zygote indeed occurs outside the female body.
- The third statement is also correct, as it lists valid examples of oviparous animals.

Since all the statements are correct, the answer to the question "Which of the following statements is not correct regarding oviparous animals?" would be:

**Answer:** None of these (Option D).

### Final Answer
The statement that is not correct regarding oviparous animals is "None of these" (Option D), as all other statements are indeed correct.
