Which of the following statements is/are incorrect?
(i) Fishes have streamlined body in order to facilitate swimming.
(ii) Birds have strong flight muscles which aid them in flying.
(iii) Snakes have hollow bones that help them in locomotion.
(iv) Tigers and wolves have sharp pointed teeth to help them tear the fleash of their prey.

Options

A. (ii) only
B. (iii) and (iv) only
C. (iii) only
D. (i) and (iii) only

Explanation

To determine which statements are incorrect, let's analyze each statement one by one:

1. **Statement (i)**: "Fishes have streamlined body in order to facilitate swimming."
- **Analysis**: A streamlined body shape is indeed characteristic of fishes. This shape helps them reduce water resistance and move efficiently through water. Therefore, this statement is **correct**.

2. **Statement (ii)**: "Birds have strong flight muscles which aid them in flying."
- **Analysis**: Birds possess strong flight muscles, particularly the pectoral muscles, which are essential for flapping their wings and enabling flight. This statement is also **correct**.

3. **Statement (iii)**: "Snakes have hollow bones that help them in locomotion."
- **Analysis**: Snakes are vertebrates and have a skeletal structure made of solid bones, not hollow bones. Hollow bones are typically found in birds to reduce weight for flight. Therefore, this statement is **incorrect**.

4. **Statement (iv)**: "Tigers and wolves have sharp pointed teeth to help them tear the flesh of their prey."
- **Analysis**: Tigers and wolves are carnivorous animals, and they possess sharp canine teeth that are specifically adapted for tearing flesh. This statement is **correct**.

**Conclusion**: The only incorrect statement is (iii) "Snakes have hollow bones that help them in locomotion."

### Step-by-Step Solution:
1. Analyze Statement (i): Fishes have streamlined bodies for swimming - **Correct**.
2. Analyze Statement (ii): Birds have strong flight muscles for flying - **Correct**.
3. Analyze Statement (iii): Snakes have hollow bones for locomotion - **Incorrect**.
4. Analyze Statement (iv): Tigers and wolves have sharp teeth for tearing flesh - **Correct**.
5. Identify the incorrect statements: Only Statement (iii) is incorrect.
