d. 3

Explanation:

Step1: Define rotational symmetry order

The order of rotational symmetry is the number of times a figure maps onto itself when rotated 360° around its center.

Step2: Analyze the given figure

Count identical triangular segments: there are 6 congruent triangular units arranged evenly around the center. Calculate rotation angle for matching: $\frac{360^\circ}{6}=60^\circ$. The figure maps to itself 6 times in a full rotation, which is 4 or more.

Answer:

B. 4 or more
