John is a software developer in FIS technology and he has used REST API in his web Application, now he wants to access a single student object in result on the basis of given ID What code snippet will he use to get the desired result?A@PostMapping("/student/{studentId}") public StudentBo getStudentById(@PathVariable int studentId)B@GetMapping("/student/{studentId)")public StudentBo getStudentById(@PathVariable int studentId)@PostMapping("/student/{studentId}") public StudentBo getStudentById(@RequestParam int studentId)@GetMappingMapping("/student/{studentId}") public StudentBo getStudentById(@RequestBody int studentId)

The correct code snippet for John to access a single student object based on the given ID would be option B:

@GetMapping("/student/{studentId)")
public StudentBo getStudentById(@PathVariable int studentId)

In this code, John is using a GET request to retrieve a student object based on the student ID passed in the URL path as a PathVariable. The @GetMapping annotation specifies the URL path for the API endpoint, and the @PathVariable annotation binds the value of the studentId parameter to the value specified in the URL. This code will return a StudentBo object containing the details of the student with the given ID.

The correct answer is option B:

@GetMapping("/student/{studentId}")
public StudentBo getStudentById(@PathVariable int studentId)

Explanation:

- `@GetMapping` is used for HTTP GET requests, which is appropriate for retrieving data.
- `"/student/{studentId}"` is the endpoint URL pattern, where `studentId` is a path variable that will be filled in with the actual student ID at runtime.
- `@PathVariable` is used to bind the value of `studentId` from the URL to the method parameter.
- `public StudentBo` specifies the return type of the method as `StudentBo`, which represents a single student object.
- The method body would contain the logic for retrieving the student object from the database or any other data source based on the given `studentId`.

Therefore, option B is the correct answer.
