The increasing order of specific charge for the following substances : electron(e), proton(p), unipositive helium atom (h), neutron (n) and a-particle is correctly represented in which of the following options?

The increasing order of specific charge for electron(e), proton(p), unipositive helium atom (h), neutron (n) and a-particle is correctly represented as e, n, p, h, a.

$\frac{q}{m}=$specific charge

For$\to \frac{e}{1840m_e} for \alpha \frac{2e}{4\times 1840m_e} ltbr gt For n\to o$

$Fore\to \frac{e}{m_e} for H{e}^{+}\to \frac{e }{4\times 1840m_e}$

Hence, correct option is B.
