The correct answer is: A. PQRS
The sentence is about the government’s failure to arrest the rise in prices. The first part of the sentence, “Though the Govt. claims,” introduces the topic of the sentence. The second part of the sentence, “the rate of inflation is down,” provides evidence that the government is not doing enough to control prices. The third part of the sentence, “or the decrease in the per capita income,” provides further evidence that the government is not doing enough to help the people. The fourth part of the sentence, “it has failed to arrest,” is the main clause of the sentence and states the main point of the sentence. The fifth part of the sentence, “the rise in prices,” is the object of the verb “arrest.” The sixth part of the sentence, “in the per capita income,” is a prepositional phrase that modifies the noun “rise.”
The other options are incorrect because they do not follow the correct sequence of events. Option B, PQSR, puts the evidence before the main point. Option C, PSQR, puts the main point before the evidence. Option D, QPSR, puts the object of the verb before the verb.
