Which of the following groups may contain a metalloid?

Options

A. IA
B. IIA
C. VIA
D. None of these

Explanation

To determine which of the given groups may contain a metalloid, we will analyze each option step by step.

### Step 1: Identify the Groups
We have the following groups:
- Option A: Alkali Metals
- Option B: Alkaline Earth Metals
- Option C: Oxygen Family

### Step 2: Understand the Nature of Each Group
- **Alkali Metals (Option A)**: This group consists of elements in Group 1 of the periodic table (e.g., Lithium, Sodium, Potassium). All of these elements are metals and do not contain metalloids.

- **Alkaline Earth Metals (Option B)**: This group consists of elements in Group 2 of the periodic table (e.g., Beryllium, Magnesium, Calcium). Similar to alkali metals, all of these elements are also metals and do not contain metalloids.

- **Oxygen Family (Option C)**: This group consists of elements in Group 16 of the periodic table (e.g., Oxygen, Sulfur, Selenium, Tellurium, and Polonium). In this group, Oxygen and Sulfur are non-metals, while Selenium and Tellurium are considered metalloids. Polonium is a metal.

### Step 3: Conclusion
Based on the analysis:
- Option A (Alkali Metals) does not contain a metalloid.
- Option B (Alkaline Earth Metals) does not contain a metalloid.
- Option C (Oxygen Family) contains metalloids (Selenium and Tellurium).

Thus, the group that may contain a metalloid is **Option C: Oxygen Family**.

### Final Answer:
**Option C: Oxygen Family**
