A developer wrote the following code:
01 let X = object.value;
02
03 try {
04 handleObjectValue(X);
05 } catch (error) {
06 handleError(error);
07 }
The developer has a getNextValue function to execute after handleObjectValue(), but
does not want to execute getNextValue() if an error occurs.
How can the developer change the code to ensure this behavior?

• A.03 try{
  04 handleObjectValue(x);
  05 } catch(error){
  06 handleError(error);
  07 }
  08 getNextValue();
• B.03 try {
  04 handleObjectValue(x)
  05 ........................
• C.03 try{
  04 handleObjectValue(x);
  05 } catch(error){
  06 handleError(error);
  07 } then {
  08 getNextValue();
  09 }
• D.03 try{
  04 handleObjectValue(x);
  05 } catch(error){
  06 handleError(error);
  07 } finally {
  08 getNextValue();
  10 }

Given the code and the information the developer has, which code logs an error at boost with an event?

• A.Server.on ('error', (error) => {
  console.log('ERROR', error);
  });
• B.Server.error ((server) => {
  console.log('ERROR', error);
  });
• C.Server.catch ((server) => {
  console.log('ERROR', error);
  });
• D.Try{
  server.start();
