Arrange the following in decreasing order of their number .
(i) Number of phalanges in each hand is 14
(ii) Total number of wrist bones in a human is 16
(iii) Total number of metacarpals in human body is 10
(iv) Number of bones in each upper limb is 30

Options

A. iv `gt` i `gt` ii `gt` iii
B. iv `gt` ii `gt` iii `gt` i
C. iv `gt` ii `gt` i `gt` iii
D. ii `gt` i `gt` iv `gt` iii

Answer

To solve the question of arranging the given numbers in decreasing order, we need to analyze each statement carefully and extract the numerical values:

1. **Number of phalanges in each hand**: 14
2. **Total number of wrist bones in a human**: 16
3. **Total number of metacarpals in the human body**: 10
4. **Number of bones in each upper limb**: 30

Now, let's list these values clearly:

- Phalanges in each hand: 14
- Wrist bones: 16
- Metacarpals in the human body: 10
- Bones in each upper limb: 30

Next, we will arrange these numbers in decreasing order:

1. **Bones in each upper limb**: 30
2. **Total number of wrist bones**: 16
3. **Number of phalanges in each hand**: 14
4. **Total number of metacarpals in the human body**: 10

Thus, the final arrangement in decreasing order is:

**30 (upper limb bones) > 16 (wrist bones) > 14 (phalanges) > 10 (metacarpals)**.

### Final Answer:
1. Number of bones in each upper limb: 30
2. Total number of wrist bones: 16
3. Number of phalanges in each hand: 14
4. Total number of metacarpals in the human body: 10
