Angular - Internationalization and Accessibility

What is wrong with this code snippet for locale switching?

import { LOCALE_ID } from '@angular/core';

providers: [
  { provide: LOCALE_ID, useValue: 'en-US' },
  { provide: LOCALE_ID, useValue: 'fr-FR' }
]

ALocale IDs must be uppercase, so 'fr-FR' is invalid.

BThe useValue must be a function returning the locale string.

CLOCALE_ID cannot be provided in providers array.

DMultiple providers for LOCALE_ID cause a conflict; only one should be provided.

Step-by-Step Solution

Solution:

Step 1: Check provider array for duplicates
Providing LOCALE_ID twice causes conflict; Angular uses the last one but this is bad practice.
Step 2: Validate other options
Locale IDs are case-insensitive; LOCALE_ID can be provided; useValue is a value, not function.
Final Answer:
Multiple providers for LOCALE_ID cause a conflict; only one should be provided. -> Option D
Quick Check:
Only one LOCALE_ID provider allowed [OK]

Quick Trick: Provide LOCALE_ID only once to avoid conflicts [OK]
