Video Summary

Anya needs to paint interconnected circles such that no two connected circles are the same color. Initially, it's clear that two colors aren't sufficient since three interconnected circles require three different colors. By using three colors—blue, green, and red—she can paint the circles following the given constraints, ensuring connected circles differ in color. Starting with the central circle in blue and others as necessary, it’s confirmed that three colors suffice for this task. Therefore, the smallest number of colors Anya needs is three, corresponding to answer choice B.
