The charge topology in the fragmentation of $^{ 10}$C nuclei in a track nuclear emulsion at an energy of 1.2 GeV per nucleon is studied. In the coherent dissociation of $^{ 10}$C nuclei, about 82% of events are associated with the channel $^{ 10}$C $\rightarrow$ 2$\alpha +$ 2\emph{ p}. The angular distributions and correlations of product fragments are presented for this channel. It is found that among $^{ 10}$C $\rightarrow$ 2$\alpha +$ 2\emph{ p} events, about 30% are associated with the process in which dissociation through the ground state of the unstable $^9$Be$_{ g.s.}$ nucleus is followed by $^8$Be$_{ g.s.} +$ \emph{ p} decays.
