C. (4)

Both intervals exclude (4), so (4) is not included. In exams, watch for missing open points even in a union.
Why this answer is correct
The correct answer is C. (4). Both intervals exclude (4), so (4) is not included. In exams, watch for missing open points even in a union.

दोनों अंतराल (4) को बाहर रखते हैं इसलिए (4) शामिल नहीं है। परीक्षा में संघ में भी खुले छूटे बिंदु पर ध्यान दें।
