Final answer:
The provided question is incomplete and lacks context, making it impossible to provide a specific English-related answer.
Step-by-step explanation:
The question "Sanjeev and Twinkle fight over ________?" seems to be incomplete as it lacks context to provide a specific answer. However, in English classes, students are often asked to fill in the blanks to test their knowledge of vocabulary, comprehension, and grammar. In literature, characters named Sanjeev and Twinkle could be involved in a conflict over a variety of issues, such as a misunderstanding, a personal possession, or differing opinions on a matter. Without additional context, it is not possible to determine the correct word or phrase to complete this sentence.
