$$6$$ and $$-6$$ are at the same distance from $$0$$ on the number line.
Correct option is A. True
Marking $$6$$ and $$-6$$ on the number line.
Distance from $$0$$ to $$6 = 6 - 0$$
$$= 6$$ units
Distance from $$0$$ to $$-6 = 0 - ( -6)$$
$$ = 6$$ units
Thus, $$6$$ and $$-6$$ are at the same distance from $$0$$.
$$\therefore$$ $$\textbf{The given statement is True}$$
