- \( \frac{e}{m_e} \) and \( \frac{e h}{2\pi m} \)
- \( \frac{m_e}{e} \) and \( \frac{e h}{2\pi m_e} \)
- \( \frac{e}{m_e} \) and \( \frac{e h}{4\pi m_e} \)

The Correct Option is A
Solution and Explanation
The gyromagnetic ratio (\( \gamma \)) is given by:
\[
\gamma = \frac{e}{2m_e},
\]
where \(e\) is the charge of the electron and \(m_e\) is the electron mass.
The Bohr magneton (\( \mu_B \)) is defined as:
\[
\mu_B = \frac{e h}{4\pi m}.
\]
