Answer #1

Answer is option: D (All of these)

a -> taking input from a redundant data source may cause error because when data fields are repeated data corruption may arise.

b -> updating a data may take more time due to duplicacy in database and finding the one that really needs updation take more time than without redundancy

c -> since you are using same data at many places in disk it will occupy extra spaces of duplicate data.

From above points all options are correct.
