Arrange natural numbers according to the following rules. Where is 2009? 1 1 column 2 column 3 column 4 column 1 line 1 2 9 10 2 lines 4 3 8 11 3 lines 5 6 7 12 Four lines 16 15 14 13 5 lines 17 ... There are four options A. Line 17, column 44 B. line 18, column 45 C. line 18, column 46 D. line 19, column 48

Connect these numbers with a broken line from small to large, and you can see the rule. The squares of even numbers are in the first column, and the squares of odd numbers are in the first row
Because 45 ^ 2 = 2025, (in line 1, column 45, line 1)
And 2025-2009 = 16
So 2009 in line 17, column 45, the given option is wrong
