On-line data entry is most appropriate when immediate, real-time updates are required—for example, which case below?

Introduction:
Online data entry suits scenarios needing immediate validation, confirmation, and posting. This question focuses on distinguishing real-time, transaction-level needs from periodic, batch-appropriate work.

Given Data / Assumptions:

• “Online” means interactive, immediate validation and update.
• Bank cheque processing often needs instant status checks and holds.
• Payroll master updates and monthly journals can be batch-oriented.

Concept / Approach:
Real-time input is justified when delay risks errors, customer dissatisfaction, or financial exposure. Banking transactions exemplify this: balances, holds, and fraud checks must be current.

Step-by-Step Solution:
1) Identify tasks needing immediacy. 2) Cheque processing requires current balances and validation. 3) Monthly journal entries are periodic and often reviewed in batch. 4) Payroll master updates usually occur in controlled cycles.

Verification / Alternative check:
Operational policies and core banking systems universally implement tellering operations as online transactions.

Why Other Options Are Wrong:
Option A: Periodic updates; immediacy rarely critical per record.
Option B: Month-end batch processing is common and adequate.
Option D: Not all listed tasks require online entry.
Option E: Incorrect because banking cheque processing is a canonical online case.

Common Pitfalls:
Assuming all accounting tasks must be online. Batch remains cost-effective for periodic work.

Final Answer:
Processing payment of a cheque in a bank (real-time validation and posting)
