Assuming the following server definition which of the answer options is correct?

const express $=$ require$(\text{'}$express$\text{'})$;

const app $=$ express$()$;

app.use$(($req$,$ res, next$)=>\{$

req.receivedTime $=$ Date.now$()$;

next$()$;

$\})$;

app.get$(\text{'}/\text{'},($req$,$ res$)=>\{$

let responseText $=$ 'Hello World!

$\text{'}$;

responseText $+=$ 'Requested at: $\text{'}+$ req.receivedTime $+\text{'}\text{'}$;

res.send$($responseText$)$;

$\})$;

app.listen$(3000)$;

Group of answer choices

req.requestTime value will be time the first request was received by the application resulting in displaying the same time value for any requests received.

req.requestTime value will be different for every request resulting in displaying the time the request was received in the response

the requestTime function will never execute since it is not called in the route handling function that is defined.
