Because your object contains a property C1, not c1. JavaScript is case-sensitive, and you need to take care of that. Use this,

JavaScript

var f = data.C1;

Since your alert is showing undefined, it clearly means that the property is undefined, the object is not. If the data was undefined, it would have said "cannot read property 'c1' of undefined". If, however, the data was of another type, then it would have said something or similar to the second error.
