Since K is an odd integer, the total number of terms (n) would be odd = 16 + K = even + odd = odd
So, Median would be the (n+1)2th term
Let's maximize the value of K;
| 1 2 3 4 5 6 | 7 8 9 10 11 12 13 14 15 16 | K
In order to have maximum number of terms, we will take the 16th term as the median
This means we will have 15 terms to it's left and 15 to the right
Therefore, k(max.) = 15
Col. A: 15
Col. B: 16
Hence, option B
