C. 2
D. 3

Answer

To determine the maximum number of unpaired electrons that can be present in a `p_x` orbital, we can follow these steps:

### Step 1: Understand the p subshell
The p subshell consists of three orbitals: `p_x`, `p_y`, and `p_z`. Each of these orbitals can hold a maximum of 2 electrons.

### Step 2: Determine the filling of the p orbitals
According to Hund's rule, when filling degenerate orbitals (orbitals of the same energy), one electron is placed in each orbital before pairing occurs. This means that if we have a p subshell that is partially filled, we can have unpaired electrons.

### Step 3: Analyze the `p_x` orbital
The `p_x` orbital can hold a maximum of 2 electrons. If there is only 1 electron in the `p_x` orbital, it will be unpaired. If there are 2 electrons, they will pair up, resulting in 0 unpaired electrons.

### Step 4: Conclusion
Thus, the maximum number of unpaired electrons that can be present in the `p_x` orbital is **1**.

### Final Answer
The maximum number of unpaired electrons in the `p_x` orbital is **1**.
