\(36a = 2k\) & \(k\) is odd

From the option, we can determine the value of \(36a\) so that \(k\) remains odd.

The only possible value for \(36a = 18\)

\(36a = 18 = 2k\)

\(k = 9\)

Answer \(B\)

Frankly I did not get the question. For me is badly worded. My opinion.

if K is odd then 2*odd must be even. But the question implies that the number should result odd.

Why not ans is 54 too, 36a = 54 = 2k ---> k = 27, which is odd.

Both B and E are correct options imo
