Match the enteries of column I with appropriate entries of column II Each entry in column I may have one or more than one correct option from column II .
`{:(,"Column I ","Column II "),((A) ,"Magnesium ",(p) p- "Block "),((B) ,"Aluminium ",(q) " Metal "),((c ) ,"Arsenic ",( r) " s- Block "),((D ) ,"Iodine ", ( s) " Metalloid "):}`

Explanation

To solve the matching problem between Column I and Column II, we will analyze each entry in Column I and identify the appropriate matches from Column II based on the properties of each element.

### Step-by-Step Solution:

1. **Identify Magnesium (A)**:
- Magnesium is located in Group 2 of the periodic table.
- It is classified as an **s-block** element because it has its last electron in the s-orbital.
- Magnesium is also a **metal**.
- **Matches**: (p) p-Block, (q) Metal, (r) s-Block.

2. **Identify Aluminium (B)**:
- Aluminium is located in Group 13 of the periodic table.
- It is classified as a **p-block** element because it has its last electron in the p-orbital.
- Aluminium is also a **metal**.
- **Matches**: (p) p-Block, (q) Metal.

3. **Identify Arsenic (C)**:
- Arsenic is located in Group 15 of the periodic table.
- It is classified as a **p-block** element.
- Arsenic is considered a **metalloid** due to its properties.
- **Matches**: (p) p-Block, (s) Metalloid.

4. **Identify Iodine (D)**:
- Iodine is located in Group 17 of the periodic table.
- It is classified as a **p-block** element.
- Iodine is a **non-metal** and is part of the halogen group.
- **Matches**: (p) p-Block.

### Final Matches:
- A (Magnesium) → (r) s-Block, (q) Metal
- B (Aluminium) → (p) p-Block, (q) Metal
- C (Arsenic) → (p) p-Block, (s) Metalloid
- D (Iodine) → (p) p-Block

### Summary of Matches:
- **A**: (r), (q)
- **B**: (p), (q)
- **C**: (p), (s)
- **D**: (p)
