Which of these is required to use matchedGeometryEffect between two views?

AA unique <code>id</code> for each view without sharing.

BA shared <code>@Namespace</code> variable.

CA <code>ViewModifier</code> applied to both views.

DA <code>Gesture</code> recognizer attached to both views.

Step-by-Step Solution

Solution:

Step 1: Identify the key requirement for matchedGeometryEffect
Both views must share the same @Namespace to link their geometry.
Step 2: Eliminate incorrect options
Unique ids without sharing namespace won't link views; gestures and modifiers are unrelated.
Final Answer:
A shared @Namespace variable. -> Option B
Quick Check:
Shared @Namespace = required for matchedGeometryEffect [OK]

Quick Trick: Use one @Namespace for all matchedGeometryEffect views [OK]
