Without the specific spectral classes and location on the Hertzsprung-Russell diagram provided, it is not possible to determine which star is most like the Sun. The spectral class alone is not enough information to make a comparison. The Hertzsprung-Russell diagram shows the relationship between a star's luminosity (or absolute magnitude) and its temperature (or spectral class). The Sun is a G-type main-sequence star with a spectral class of G2V. A comparison of the spectral classes and positions on the Hertzsprung-Russell diagram would be necessary to determine which star is most similar to the Sun.
