The correct code snippet to access a single student object in result based on the given ID is:
```java
@GetMapping("/student/{studentId}")
public StudentBo getStudentById(@PathVariable int studentId) {
// code to retrieve the student object based on studentId
// and return it
}
```
In this code snippet, we are using the `@GetMapping` annotation to map the HTTP GET request to the `/student/{studentId}` URL pattern. The `{studentId}` placeholder is replaced with the actual student ID value passed in the URL. We are using the `@PathVariable` annotation to bind the `studentId` parameter to the value passed in the URL.
Using `@RequestParam` or `@RequestBody` annotations would not be appropriate here, as they are used for different types of parameters. `@PostMapping` annotation is used to map HTTP POST requests, so it is also not appropriate in this case.
