A triangle is dilated by a scale factor of n = One-third. Which statement is true regarding the dilation?It is a reduction because n > 1.It is a reduction because 0 < n < 1.It is an enlargement because n > 1.It is an enlargement because 0 > n > 1.

Since the scale factor is between 0 and 1, that means the dilation will decrease the figure size (it's a reduction and not a enlargement).
Therefore the correct option is the second one.
