consider the following statements and mark them as true/false.
I. The eggs laid by alligator are cleidoic eggs.
II. The eggs laid by Panthera leo are non-cleidoic nature.
III. Platypus is an oviparous mammal.
IV. The chances of survival of young ones is less in viviparous organisms.
Choose the correct codes.

Options

A. `{:("I","II","III","IV"),("True","False","False","True"):}`
B. `{:("I","II","III","IV"),("True","False","True","False"):}`
C. `{:("I","II","III","IV"),("True","True","False","False"):}`
D. `{:("I","II","III","IV"),("False","False","True","False"):}`

Answer

To solve the question, we need to evaluate each of the four statements provided and determine whether they are true or false. Let's go through each statement step by step:

### Step 1: Evaluate Statement I
**Statement I:** The eggs laid by alligator are cleidoic eggs.

- **Explanation:** Cleidoic eggs are characterized by a hard protective covering and are laid out of water. Alligators, which are reptiles, lay eggs that have a hard shell, thus they are indeed cleidoic eggs.
- **Conclusion:** This statement is **True**.

### Step 2: Evaluate Statement II
**Statement II:** The eggs laid by Panthera leo are non-cleidoic in nature.

- **Explanation:** Panthera leo, commonly known as the lion, is a mammal. Mammals typically have cleidoic eggs, which means they have a protective covering and are not laid in water. Therefore, the eggs of Panthera leo are not non-cleidoic.
- **Conclusion:** This statement is **False**.

### Step 3: Evaluate Statement III
**Statement III:** Platypus is an oviparous mammal.

- **Explanation:** Oviparous mammals are those that lay eggs. The platypus is indeed an exception among mammals as it lays eggs instead of giving birth to live young. Therefore, this statement is correct.
- **Conclusion:** This statement is **True**.

### Step 4: Evaluate Statement IV
**Statement IV:** The chances of survival of young ones is less in viviparous organisms.

- **Explanation:** Viviparous organisms give birth to live young, which typically have a higher chance of survival compared to those that hatch from eggs (oviparous). Thus, this statement is misleading.
- **Conclusion:** This statement is **False**.

### Final Summary of Statements
1. Statement I: True
2. Statement II: False
3. Statement III: True
4. Statement IV: False

### Correct Codes
Based on the evaluations:
- The correct codes for the statements are: I - True, II - False, III - True, IV - False.
