Aasync getItem(@Body('id') id: string) {}

Basync getItem(@Query('id') id: string) {}

Casync getItem(@Param('id') id: string) {}

Dasync getItem(@Headers('id') id: string) {}

Step-by-Step Solution

Solution:

Step 1: Identify the decorator for route parameters
@Param is used to extract parameters from the URL path, such as /items/:id.
Step 2: Check other decorators and their uses
@Body extracts data from the request body, @Query from query strings, and @Headers from HTTP headers, so they don't get route params.
Final Answer:
async getItem(@Param('id') id: string) {} -> Option C
Quick Check:
Route param = @Param [OK]
