I is correct. Article A should not come before grievance redress because grievance redress is not separate from social audit, it is modifying social audit and The phrase "social audit and grievance redress" is a noun phrase that functions as the object of the preposition "provides for" in the original sentence. For example: I provide for the well-being and financial security of my family. Here financial security is a part of well-being and hence will not take a separate article. II. The date also marks the commencement of the centenary year of the Vaikom temple street entry movement that was launched in 1924, and a milestone in temple entry movements in India. So while "century" refers to a period of 100 years, "centenary" refers to a specific point in time that is 100 years after a significant event, or 100^th anniversary. III. Put IS after important.
