  1. c
  2. To clean data, removing outliers, remove unnecessary columns,scaling of features, ML algorithms deal with numerical values only for that encoding also required, Get the relations between the features etc. To acheive all the above we require data pre-processing.
    4.there are four types of Machine learining:

supervised machine learning
unsupervised machine learning
Reinforced learning
semi-supervised machine learning


Amazing guys @thirumal202018 @brindhubala30
