The true statement is (b) It is a reduction because 0 < n < 1.
The scale factor of dilation is given as:
n = 1/3
When the scale factor (n) is between 0 and 1, then the dilation is considered reduction or compression;
Otherwise, the dilation is considered enlargement or stretch
Because n is between 0 and 1, then the dilation is a reduction
Hence, the true statement is (b) It is a reduction because 0 < n < 1.
