Answer
$S$ is not a basis for $R^3$.
Work Step by Step
The set$S=\{(0,0,0),(1,3,4),(6,1,-2)\}$
for $R^{3}$
is not a basis for $R^3$ because $S$ is not linearly independent set of vectors. Indeed, assume that
$$a(0,0,0)+b(1,3,4)+c(6,1,-2)=(0,0,0), \quad a,b,c\in R.$$
One can see that the above combination is true for the choice $a\neq 0, b=c=0$. This means that $S$ is Linearly independent.
