var animal = { name : "Zebra", lifeSpan: 25, weight: 770 };
Which of the following code examples would change the weight property of the animal object?
A
weight = 770;
B
zebra.weight = 770;
C
animal['weight'] = 770;
For the question above, the answer (according to the video) should be as follows: animal.weight = ...
However, as you can see, it´s not even listed. After taking the quiz 2 times I now know that the correct answer (according to the quiz) is answer C, however this isn´t representative of what is explained in the video whatsoever. I´m well confused at this point. Any comment?

These ways are known as dot and bracket notation.
Dot is the way you've identified. where you set object.property. But with Bracket notation, you use object["property"] or object["property"] = value
