(B) The specific charge ($e/m$ ratio) is calculated as follows:$1$. For an electron $(e)$: Charge = $-1$,Mass $\approx \frac{1}{1837} \ amu$. Ratio $\approx 1837$.$2$. For a proton $(p)$: Charge = $+1$,Mass $\approx 1 \ amu$. Ratio = $1$.$3$. For an alpha particle $(\alpha)$: Charge = $+2$,Mass $\approx 4 \ amu$. Ratio = $0.5$.$4$. For a neutron $(n)$: Charge = $0$,Mass $\approx 1 \ amu$. Ratio = $0$.Comparing these values,the electron has the highest $e/m$ ratio.

The ratio of charge to mass ($e/m$ ratio) is greatest for which of the following particles?
