Total number of rows = 12-0+1 = 13
Total number of columns = 12-0+1 = 13
Body will contain 169 elements.
Only Odd*Odd = Odd.
So the total number of odd products in each row = 6 (6 even and 6 odd products)
And we need to reject the even columns, as the products will all be even.
Hence the numbers of columns with odd products = 6
Total odd products in body = 6*6 = 36

Fraction of odd in the body = 36/169

36*4 = 144
144+18 = 162 = almost equal to 4.5 times 36

36/169 = 1/4.5 = 1/(9/2) = 2/9 = 0.22 (1/9 = 0.1111)

Hence A is the closest answer.

Since there are 13 (0 to 12, inclusive) rows and 13 columns, there are 169 products (necessarily distinct). The product of two numbers is odd if both numbers are odd. There are 6 (i.e., 1, 3, 5, 7, 9, 11) odd numbers from 0 to 12, so there are 6 rows and 6 columns of odd numbers, creating 6 x 6 = 36 odd products. Therefore, the fraction of the products that are odd is 36/169 ≈ 0.21.

Answer: A
