If \overrightarrow{a} is a colinear vector with \overrightarrow{b}=3 \stackrel{\^}{i}+6 \stackrel{\^}{j}+6 \stackrel{\^}{k} and {a} ^{\to}\.\overrightarrow{b}=27. Then, \overrightarrow{a} is

3(\stackrel{\^}{i}+\stackrel{\^}{j}+\stackrel{\^}{k})

2(\stackrel{\^}{i}+\stackrel{\^}{j}+\stackrel{\^}{k})

\stackrel{\^}{i}+2 \stackrel{\^}{j}+2 \stackrel{\^}{k}

2 \stackrel{\^}{i}+3 \stackrel{\^}{j}+3 \stackrel{\^}{k}
