An element of group 14 forms two oxides one of which is highlty poisionous and neutral. Other oxide can be easily liquefied and compressed to give a solid which is used as a refrigerant under the name of drikold. The element and the oxides are

Options

A. `Si,SiO,SiO_(2)`
B. `Pb,PbP,PbO_(2)`
C. `C,CO,CO_(2)`
D. `Sn,SnO,SnO_(2)`

Explanation

To solve the question, we need to identify the element from group 14 and its two oxides based on the given characteristics. Let's break down the solution step by step.

### Step 1: Identify the Group 14 Element
Group 14 of the periodic table includes elements like Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb). We need to focus on the oxides formed by these elements.

**Hint:** Look for the element that can form both a neutral oxide and an oxide that can be liquefied and compressed.

### Step 2: Analyze the Oxides
Group 14 elements can form oxides in two oxidation states:
- MO (monoxide)
- MO2 (dioxide)

We need to find an element that forms one oxide which is neutral and poisonous, and another oxide that can be easily liquefied.

**Hint:** Recall the properties of common oxides of Group 14 elements.

### Step 3: Identify the Neutral and Poisonous Oxide
Among the common oxides:
- Carbon monoxide (CO) is a neutral oxide and is highly poisonous.
- Other neutral oxides include silicon monoxide (SiO), but it is not known for being poisonous.

**Hint:** Think about how carbon monoxide interacts with hemoglobin in the blood, making it poisonous.

### Step 4: Identify the Liquefiable Oxide
The other oxide we are looking for must be able to be easily liquefied and compressed. Carbon dioxide (CO2) fits this description as it can be liquefied under certain conditions and can solidify into dry ice (solid CO2), which is used as a refrigerant.

**Hint:** Consider the uses of carbon dioxide in refrigeration and food preservation.

### Step 5: Conclusion
Based on the analysis:
- The element is **Carbon (C)**.
- The two oxides are:
1. Carbon monoxide (CO) - neutral and highly poisonous.
2. Carbon dioxide (CO2) - can be liquefied and compressed to form dry ice (Dricold).

Thus, the answer is:
- **Element:** Carbon (C)
- **Oxides:** Carbon monoxide (CO) and Carbon dioxide (CO2)

### Final Answer:
The element is Carbon (C) and the oxides are Carbon monoxide (CO) and Carbon dioxide (CO2).
