C) 6 |

Description for Correct answer:

For infinite solution

\( \Large \frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}} \)

= \( \Large \frac{K}{12}=\frac{3}{K}=\frac{-K+3}{-K} \)

= \( \Large \frac{K}{12}=\frac{3}{K}=K^{2}=36 \)

Therefore, \( \Large K = \sqrt{36} = 6 \)

For infinite solution

\( \Large \frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}} \)

= \( \Large \frac{K}{12}=\frac{3}{K}=\frac{-K+3}{-K} \)

= \( \Large \frac{K}{12}=\frac{3}{K}=K^{2}=36 \)

Therefore, \( \Large K = \sqrt{36} = 6 \)
