Final Answer : C, Explanation :   Option C represents a fusion reaction where two hydrogen nuclei (  1 1 H { }_{1}^{1} \mathrm{H} 1 1 ​ H  ) combine to form a deuterium nucleus (  1 2 H { }_{1}^{2} \mathrm{H} 1 2 ​ H  ), releasing a positron (  1 0 e { }_{1}^{0} \mathrm{e} 1 0 ​ e  ) in the process. Fusion involves combining lighter nuclei to form a heavier nucleus, which is exemplified in this option.
