What is the simplest way to address the missing value problem in data science applications? O a. Replace all the missing values in each column by some fixed value O b. Delete all the columns from the Data Frame in which even a single missing value exists O . Delete all the rows from the Data Frame in which even a single missing value exists O d. Replace the missing values in each column by the mean of each column
