Validation: Cross-verify cleaned data against original sources for accuracy.
                       Quality Assurance: Ensure data consistency and document cleaning steps for transparency.
                       Export: Save cleaned dataset in a suitable format (e.g., CSV) for analysis.
                       Final Check: Validate data integrity post-export to ensure reliability for analysis.
                    2.   Assertion and Reasoning Questions:
                          Direction: Question 2, consist of two statements – Assertion (A) and Reasoning (R). Answer these questions by selecting
                       the appropriate option given below:
                       (a) Both A and R are true and R is the correct explanation of A.
                       (b) Both A and R are true but R is not the correct explanation of A.
                       (c) A is true but R is false.
                       (d) A is false but R is true.
                       Assertion (A): Cleaning data is a crucial step in the data analysis process.
                         Reasoning  (R):  Data  cleaning  ensures  that  the  dataset  is  free  from  errors,  duplicates,  and  missing  values,  which
                       enhances the reliability and accuracy of subsequent analysis.
