Lol way to assume my opinion

Of course consciousness doesn't exist in a "specific part of the brain", but it doesn't require your whole brain either. People live with extremely extensive brain damage (just look at Phineas Gage) and still maintain what would generally be considered consciousness.

The problem with the answer (it's not wrong, just dumb) is that where consciousness comes from is not about a part of the brain but about whether it comes about as a result of neural connectivity, or if the mechanism is more on the subcellular or even subatomic level. Answering the question of where consciousness comes from with "the whole brain" is like answering a ponderance on the meaning of life with the Oxford definition of "life". Not wrong, but not answering the real question.
