Why this answer is correct
The correct answer is C. \(\emptyset\). The first part goes up to (-2), and the second starts after (-2), so there is no common point. In exams, decide intersection after checking endpoint inclusion.
Exam Tip
पहला भाग (-2) तक है और दूसरा (-2) के बाद शुरू होता है, इसलिए कोई common point नहीं है। परीक्षा में endpoint inclusion देखकर intersection तय करें।
