Angular - Performance Optimization

Given this Angular component snippet, what will be the effect on performance? @Component({ selector: 'app-sample', changeDetection: ChangeDetectionStrategy.Default }) export class SampleComponent { data = [1, 2, 3]; }

AAngular checks for changes only when inputs change

BAngular runs change detection on every event

CAngular disables change detection

DAngular skips change detection entirely

Default strategy runs change detection on every event, checking all bindings.
Step 2: Compare with other strategies
OnPush limits checks to input changes; Default does not.
Final Answer:
Angular runs change detection on every event -> Option B
Quick Check:
Default strategy = checks every event [OK]

Quick Trick: Default strategy triggers checks on all events [OK]

Common Mistakes:

Confusing Default with OnPush behavior
Thinking Default disables detection
Assuming detection skips without inputs
