Which one of the following items gives its correct total number

Options

A. Types of diabetes - 3
B. Cervical vertebrae in humans- 8
C. Floating ribs in humans - 4
D. Amino acids found in proteins - 16

Answer

To solve the question regarding which item gives its correct total number, we will analyze each option provided:

1. **Type of diseases**:
- The question mentions "type of disease" and states that there are 3 types. However, when we consider diabetes, there are primarily two recognized types: Type 1 and Type 2. Therefore, this option is incorrect.

2. **Cervical vertebrae in humans**:
- The question states that there are 8 cervical vertebrae. However, in humans, there are actually 7 cervical vertebrae (C1 to C7). Thus, this option is also incorrect.

3. **Floating ribs in humans**:
- The question mentions that there are 4 floating ribs. In humans, there are indeed 4 floating ribs, which are the 11th and 12th pairs of ribs. This option is correct.

4. **Amino acids found in proteins**:
- The question states that there are 16 amino acids found in proteins. However, there are 20 standard amino acids that are used to build proteins in the human body. Therefore, this option is incorrect.

Based on the analysis above, the correct answer to the question is:

**Floating ribs in humans, which are 4 in number.**
