Answer: Option C
Answer: (c)In order to arrive at the conclusion, let us try to justify by replacing the phrase in bold with the given options one by one. On replacement with option (a) the sentence becomes : "Your bonus is dependable the quality...." (omission of ‘on’) On replacement with option (b): "Your bonus depends on the quality...." (correct) . On replacement with option (c) : "Your bonus being depends on the quality...." (sentence changed to a conditional sentence, and also, depends is incorrect). On replacement with option (d) : "Your bonus going to depend on the quality...." (omission of auxiliary verb ‘is’) It is clear that option (b) is the only correct option.
