Suppose we want to re$-$scale our data using MinMaxScaler:

from sklearn.preprocessing import MinMaxScaler

MyScaler $=$ MinMaxScaler$()$

What should be A and B in the following lines of codes?

X$\_$train$\_$scaled $=$ MyScaler.A$($X$\_$train$)$

X$\_$test$\_$scaled $=$ MyScaler.B$($X$\_$test$)$

Group of answer choices

A $=$ fit$\_$transform, B $=$ transform

A $=$ transform, B $=$ transform

A $=$ fit$\_$transform, B $=$ fit$\_$transform

A $=$ transform, B $=$ fit$\_$transform
