Correct option is A
Option (A) contains a grammatical error.
Detailed explanation of the error:
The error is the use of the definite article “the” in the phrase “has won the elections”.
Here, “elections” is used in a general sense (meaning: he has won elections earlier in his career). In such cases, we do not use “the” because “the” points to a specific, already-known election.
If the speaker meant a particular election (for example, “the 2024 election”), then “the election” could be correct. But the sentence says “elections before”, which clearly indicates multiple elections in general, not one specific election.
Therefore, the correct sentence should be:
“He has won elections before, but this time the situation is different.”
Grammatical rule used (Article Rule):
Use “the” when referring to something specific/particular that is already known or has been mentioned.
Do not use an article (zero article) when talking about things in a general sense, especially plural nouns like elections, books, cars, exams, etc.
Example (to understand the rule):
General meaning: He reads books. (books in general)
Specific meaning: He reads the books you gave him. (specific books)
