Hydrogen has the tendency to gain one election to acquire helium configuration, in this respect, it resembles:

Options

A. alkali metals
B. carbon
C. alkaline earth metals
D. halogens

Explanation

To solve the question, "Hydrogen has the tendency to gain one electron to acquire helium configuration, in this respect, it resembles:", we will analyze the electronic configurations of hydrogen and the other elements mentioned in the options.

### Step-by-Step Solution:

1. **Understanding Hydrogen's Electron Configuration**:
- Hydrogen (H) has an atomic number of 1, which means it has 1 electron. Its electron configuration is 1s¹.
- To achieve a stable electron configuration similar to helium (He), which has an atomic number of 2 and an electron configuration of 1s², hydrogen can gain one electron to become H⁻.

2. **Identifying the Resembling Elements**:
- We need to find an element that also tends to gain one electron to achieve a stable electron configuration similar to that of an inert gas.

3. **Analyzing Alkali Metals**:
- Alkali metals (e.g., sodium, Na) have an electron configuration of [Noble Gas] ns¹.
- When they gain one electron, they become [Noble Gas] ns², which is not the configuration of an inert gas but that of alkaline earth metals. Thus, alkali metals do not resemble hydrogen.

4. **Analyzing Carbon**:
- Carbon (C) has an atomic number of 6, with an electron configuration of 1s² 2s² 2p².
- Carbon needs four electrons to achieve the inert gas configuration of neon (Ne), so it does not resemble hydrogen in this aspect.

5. **Analyzing Alkaline Earth Metals**:
- Alkaline earth metals (e.g., magnesium, Mg) have an electron configuration of [Noble Gas] ns².
- They do not gain just one electron to achieve an inert gas configuration; they lose two electrons instead. Therefore, they do not resemble hydrogen.

6. **Analyzing Halogens**:
- Halogens (e.g., fluorine, F) have an atomic number of 9, with an electron configuration of 1s² 2s² 2p⁵.
- Halogens need one electron to achieve the stable configuration of the nearest noble gas, which is neon (Ne). Therefore, they resemble hydrogen in their tendency to gain one electron.

7. **Conclusion**:
- The element that resembles hydrogen in its tendency to gain one electron to achieve a stable inert gas configuration is a halogen, specifically fluorine.

### Final Answer:
The correct option is **D. Halogens**.
