**Question:**

In mass spectrometry, a peak formed from the dissociation of the initial unstable radical cation is called a

**Options:**

A) base peak.  
B) fragment ion.  
C) molecular ion.

---

**Explanation:**

In the context of mass spectrometry:

- **Base Peak**: The tallest peak in the mass spectrum, representing the most abundant ion.
  
- **Fragment Ion**: Ions that result from the breakup of the molecular ion, often providing structural information about the molecule.
  
- **Molecular Ion**: The ion formed by removing an electron from the molecule, often representing the entire molecule.

In this question, the focus is on identifying which term describes the peak formed after the initial radical cation dissociates.
