Possible cases:
1. N before 100 ----- median is $$\frac{(140+180)}{2}$$ = 160 i.e., $$\frac{(3rd +4th)}{2}$$ Similarly,
2. N before 140 ----- median is $$\frac{(140+180)}{2}$$ = 160
3. N before 180 ----- median is $$\frac{(n+180)}{2}$$ = $$\frac{(180+n)}{2}$$
4. N before 220 ----- median is $$\frac{(180+n)}{2}$$ = $$\frac{(180+n)}{2}$$
5. N before 260 ----- median is $$\frac{(180+220)}{2}$$ = 200
6. N after 260 ----- median is $$\frac{(180+220)}{2}$$ = 200

Hence , ans C
