Redundancy is the mechanism that occurs in database's data as the same data is stores in the multiple location.It creates repeated data by accident or for backup purpose.
The issues that arise due to the redundancy of the data is the storage space in database gets consumed and thus wastes the space in storing information in multiple locations.When any update occurs in the stored data's field value , it also has to be changed in the multiples occurrences.

Option D is also incorrect because both are able to self replicate.
Roman numerals are V for 5, X for 10, L for 50, C for 100, D for 500, and M for 1,000.
Recall that some numbers are formed by using a kind of subtraction of one Roman “digit”; for example, IV is 4 produced as V minus I, XL is 40, CM is 900, and so on.
A few sample years: MCM is 1900, MCML is 1950, MCMLX is 1960, MCMXL is 1940, MCMLXXXIX is 1989.
(Hints: Use division and mod.)
Assume the year is between 1000 and 3000.
