To determine which tables will not tilt when subjected to a small perturbation in any direction, we need to assess the stability of each design. A stable table generally has the following characteristics: a low center of gravity, wide base, and even weight distribution.
First, consider the stability aspects:
Wide Base: The base of the table should be broad enough to resist tipping.
Low Center of Gravity: A lower center of gravity enhances stability.
Even Weight Distribution: The weight needs to be distributed evenly across the table to prevent tilting from minor shifts.
Upon analyzing the designs:

Characteristics
Stability
High center of gravity, narrow legs
Unstable
Moderately wide base, uneven weight distribution
Possibly Unstable
Wide base, low center of gravity
Stable
Wide base, even weight distribution
Stable
Based on these characteristics, and are the tables that will not tilt when given a small perturbation in any direction due to their stable design.
