Select the option that correctly fills any four blanks in the above paragraph.

Options

A. (ii)-Ulna, (iv)-Fibula, (vi)-Tibia, (viii)-Tarsals
B. (i)-Radius, (iii)-Humerus, (v)-Tibia, (vii)-Clavicle
C. (i) - Humerus, (ii)-Radius, (iv)-Femur, (vii)-Metacarpals
D. (ii)-Ulna, (iii)-Radius, (v)-Femur, (vi)-Scapula

Explanation

To fill in the blanks in the given paragraph about the human skeleton, we can follow these steps:

1. **Identify the long bone of the upper arm**: The long bone in the upper arm is known as the **humerus**.
- **Hint**: Think about the bone that connects the shoulder to the elbow.

2. **Identify the long bones of the lower arm**: The two long bones in the lower arm are the **radius** and **ulna**.
- **Hint**: These bones are located between the elbow and the wrist.

3. **Identify the long bone of the upper leg**: The long bone in the upper leg is called the **femur**.
- **Hint**: This is the longest bone in the human body.

4. **Identify the long bones of the lower leg**: The two long bones in the lower leg are the **tibia** and **fibula**.
- **Hint**: The tibia is the larger bone, often referred to as the shinbone.

5. **Identify the bones of the wrist and hands**: The bones of the wrist are called **carpals**, and the long bones in the hand are known as **metacarpals**.
- **Hint**: Carpals are the small bones that make up the wrist.

6. **Identify the bones of the ankle and feet**: The bones in the ankle and feet are called **tarsals**, along with **metatarsals** and **phalanges**.
- **Hint**: Tarsals are the bones that form the ankle.

Now, we can fill in the blanks in the paragraph:

- (i) **humerus**
- (ii) **radius**
- (iii) **ulna**
- (iv) **femur**
- (v) **tibia**
- (vi) **fibula**
- (vii) **metacarpals**
- (viii) **tarsals**

Thus, the completed paragraph would read:

"The human skeleton consists of many different long and short bones. The upper arm consists of a long bone called **humerus** whereas **radius** and **ulna** are the long bones of the lower arm. **Femur** is the long bone of the upper leg whereas the lower leg consists of two long bones called **tibia** and **fibula**. Carpals, **metacarpals** and phalanges are bones of the wrist and hands whereas the ankle and feet have bones called **tarsals**, metatarsals and phalanges."
