                      The following questions consist of two statements – Assertion (A) and Reason (R). Answer these questions by
                    selecting the appropriate option given below:
                     i.  Both A and R are true and R is the correct explanation of A.
                    ii.  Both A and R are true but R is not the correct explanation of A.
                    iii. A is true but R is false.

                       Reason (R): This finger positioning facilitates efficient typing without disrupting the natural resting position of
                       the fingers on the home row.
