@Component({ selector: 'app-test', template: `

{{ title }}

` }) export class TestComponent { title: string; }
AIncorrect selector name format
BMissing initialization of the 'title' property
CTemplate syntax should use square brackets instead of curly braces
DClass should not be exported
Step-by-Step Solution
Solution:
  1. Step 1: Check property declaration

    The title property is declared but not initialized, so it is undefined at runtime.

    Angular tries to display {{ title }}, but since title is undefined, it will render empty or cause issues.
  3. Final Answer:

    Missing initialization of the 'title' property -> Option B
  4. Quick Check:

    Uninitialized property causes undefined display [OK]
Quick Trick: Always initialize component properties before use [OK]
Common Mistakes:
  • Thinking selector format is wrong
  • Confusing Angular interpolation syntax
  • Believing export keyword is disallowed
