He said P : here is the cat Q : throughout the night R : which had been paying havoc with things S : that ate the rat The Proper sequence should be:

The correct answer is A. PSQR.

The sentence is about a cat that ate a rat. The cat had been paying havoc with things throughout the night. The speaker is saying that the cat is here.

The sentence can be broken down into the following clauses:

1. He said.
2. Here is the cat.
3. Which had been paying havoc with things.
4. Throughout the night.
5. That ate the rat.

The correct sequence of the clauses is PSQR. This is because the first clause, “He said,” introduces the speaker. The second clause, “Here is the cat,” identifies the subject of the sentence. The third clause, “Which had been paying havoc with things,” provides additional information about the cat. The fourth clause, “Throughout the night,” specifies when the cat was paying havoc with things. The fifth clause, “That ate the rat,” provides the final piece of information about the cat, namely that it ate a rat.

The other options are incorrect because they do not follow the correct sequence of the clauses. Option B, PSRQ, puts the third clause before the second clause. Option C, QPRS, puts the fourth clause before the second clause. Option D, QRPS, puts the fifth clause before the second clause.
