A? Really? Normalization has nothing to do with min and max values. Sounds like someone needs to go back to their machine learning basics.

D is definitely true. Normalization can be affected by outliers in the data, so we need to be careful about that.

Option C is interesting, but I'm not sure if that's the correct answer. I'll have to double-check the documentation.

I believe option D) Normalization got affected by outliers is also important to consider, as outliers can skew the normalization process.
