Computerized periodical records are covered in:

The question pertains to the specific legal provision covering the computerization of land records, particularly periodical records. Section 41-B is the correct answer because, in many land revenue acts, this section is specifically introduced or amended to address the modernization and computerization of land records, including the maintenance of periodical records in digital format.

• Section 41-A typically deals with other aspects of land records, such as their preparation or maintenance, but not specifically computerization.
• Section 40 and Section 43 would cover different provisions within the relevant act, unrelated to the computerization of records.

Thus, Section 41-B is the designated provision for computerized periodical records.
