He sat P : through the Town Hall Park Q : which flanked a path running R : under the boughs S : of a spreading tamarind tree The Proper sequence should be:

The correct answer is D. PRSQ.

The sentence is about a man who is sitting under a tamarind tree in Town Hall Park. The tree is located on a path that runs through the park. The man is sitting on the path, under the tree.

The first option, PQSR, is incorrect because it places the phrase “which flanked a path running” before the phrase “under the boughs of a spreading tamarind tree.” This is incorrect because the path is located under the tree, not the other way around.

The second option, RSQP, is incorrect because it places the phrase “under the boughs of a spreading tamarind tree” before the phrase “which flanked a path running.” This is incorrect because the tree is located on the path, not the other way around.

The third option, RSPQ, is incorrect because it places the phrase “under the boughs of a spreading tamarind tree” after the phrase “He sat.” This is incorrect because the man is sitting under the tree, not the other way around.

The fourth option, PRSQ, is the correct answer because it places the phrases in the correct order. The man is sitting on the path, which runs under the tree in Town Hall Park.
