Answer 1

Q3:

Ans:

Option (a) is incorrect because we are parsing the object from the "res" variable using: var name =JSON.parse(res.body).name; but we will get the JSON object in the "req" variable.

Option (b) is incorrect because we are not even parsing the response object and directly using: var name = req.body.name; but , we will get the required value by parsing the object inside the "req" variable using JSON.parse()

Option (c) is correct because we are getting the object from the correct variable i.e, the "req" variable and also parsing the object to get the value of the "name" key.

Option (d) is incorrect because it is nether using the correct correct variable "req" nor it is parsing the variable.
