The question is "For some constant real numbers \(p, k\) and \(a\), consider the following system of linear equations in \(x\) and \(y\) : $$ \begin{aligned} & p x-4 y=2 \\ & 3 x+k y=a \end{aligned} $$ A necessary condition for the system to have no solution for \((x, y)\), is "

Hence, the answer is '\(2 a+k \neq 0\)'

Choice A is the correct answer.
