Which part is incorrect in the given sentence ?

Question

Accepted Answer

Option 3 is incorrect because the verb "do" does not agree with the subject "opinion." The subject "opinion" is singular, so the verb should be "does." The correct phrasing would be "opinion does not stop at political boundaries."

Here's why the other options are incorrect:

*   **Option 1: "As far as the export of wildlife is concerned."** This phrase is grammatically correct and sets the context for the sentence. It introduces the topic being discussed.

*   **Option 2: "this is luckily a subject on which opinion."** This phrase is grammatically sound. It correctly introduces the subject of opinion.

*   **Option 4: "Thinking people of Europe are just as disturbed by the depletion of Indian wildlife as we are."** This phrase is grammatically correct and logically follows the preceding clauses. It expresses a comparison of concern between Europeans and the speakers regarding Indian wildlife depletion.
