Explanation

To solve the matching question between Column I and Column II, we will analyze each element in Column I and match it with the appropriate category in Column II.

### Step-by-Step Solution:

1. **Identify the elements in Column I:**
- (A) He, Ne, Ar
- (B) Fr, Ra
- (C) Ce, Gd, Yb
- (D) Rb, Ga, Cl

2. **Match (A) He, Ne, Ar:**
- These elements are known as noble gases. They belong to Group 18 of the periodic table.
- **Match:** (A) → (r) Noble gases

3. **Match (B) Fr, Ra:**
- Francium (Fr) and Radium (Ra) are known to be radioactive elements. They are located in the alkali metal and alkaline earth metal groups, respectively, and are known for their radioactivity.
- **Match:** (B) → (s) Radioactive elements

4. **Match (C) Ce, Gd, Yb:**
- Cerium (Ce), Gadolinium (Gd), and Ytterbium (Yb) are part of the lanthanoid series, which are f-block elements.
- **Match:** (C) → (q) Lanthanoids

5. **Match (D) Rb, Ga, Cl:**
- Rubidium (Rb), Gallium (Ga), and Chlorine (Cl) are representative elements. They belong to the s-block and p-block of the periodic table.
- **Match:** (D) → (p) Representative elements

### Final Matches:
- (A) → (r) Noble gases
- (B) → (s) Radioactive elements
- (C) → (q) Lanthanoids
- (D) → (p) Representative elements

### Summary of Matches:
- (A) He, Ne, Ar → (r) Noble gases
- (B) Fr, Ra → (s) Radioactive elements
- (C) Ce, Gd, Yb → (q) Lanthanoids
- (D) Rb, Ga, Cl → (p) Representative elements
