From the given molecular model, we can observe that the central atom (S) has four regions of electron density (two single bonds and two lone pairs) arranged in a tetrahedral geometry. The two S-Cl bond angles will be less than 90° (closer to 85°) due to lone pair repulsion. The S-S-Cl bond angle will be greater than 120° but less than 180° due to repulsion between the lone pair on one S atom and the Cl atom on the other. Finally, the S-S-S bond angle will be 180°, as they form a linear geometry. Therefore, the correct answer is C.
