Q1

If the system of equations
\[
\begin{aligned}
& x+2 y+3 z=3 \\
& 4 x+3 y-4 z=4 \\
& 8 x+4 y-\lambda z=9+\mu
\end{aligned}
\]
has infinitely many solutions, then the ordered pair \((\lambda, \mu)\) is equal to

a

\(
\left(\frac{72}{5}, \frac{21}{5}\right)
\)

b

\(
\left(\frac{-72}{5}, \frac{-21}{5}\right)
\)

c

\(
\left(\frac{72}{5}, \frac{-21}{5}\right)
\)

d

\(
\left(\frac{-72}{5}, \frac{21}{5}\right)
\)
