Question 4

Assertion. A dataframe is value mutable and size-mutable.

Reason. All changes occur in-place in a dataframe.

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

Both A and R are true and R is the correct explanation of A.

Explanation
A DataFrame is a two-dimensional data structure that is both value-mutable and size-mutable. This means that we can modify the values within a DataFrame, change its size in place once it's created, and add or drop elements in an existing DataFrame object without creating a new DataFrame internally.
