The Halogen which is solid at room temperature is

Options

A. `I_(2)`
B. `Br_(2)`
C. `Cl_(2)`
D. `F_(2)`

Explanation

To determine which halogen is solid at room temperature, we can follow these steps:

### Step 1: Identify the Halogens
The halogens include:
- Fluorine (F2)
- Chlorine (Cl2)
- Bromine (Br2)
- Iodine (I2)

### Step 2: Determine the State of Each Halogen at Room Temperature
- **Fluorine (F2)**: At room temperature, fluorine exists as a gas.
- **Chlorine (Cl2)**: Chlorine is also a gas at room temperature.
- **Bromine (Br2)**: Bromine is a liquid at room temperature.
- **Iodine (I2)**: Iodine is solid at room temperature.

### Step 3: Conclusion
From the analysis above, the only halogen that is solid at room temperature is **Iodine (I2)**.

### Final Answer
The halogen which is solid at room temperature is **I2 (Iodine)**.
