The system of linear equations
\[
\begin{array}{l}
\lambda x+2 y+2 z=5 \\
2 \lambda x+3 y+5 z=8 \\
4 x+\lambda y+6 z=10 \text { has }
\end{array}
\]
\( \mathrm{P} \)
W
(1) No solution when \( \lambda=8 \)
(2) A unique solution when \( \lambda=-8 \)
(3) No solution when \( \lambda=2 \)
(4) Infinitely many solutions when \( \lambda=2 \)
