Customer behavior in the banking sector is frequently influenced by changes in government policy and digital infrastructure. Statement 1: A Marketing Information System (MKIS) that performs a longitudinal analysis of the Unified Payments Interface (UPI) transactions since its inception in 2016 would show a clear transition from small P2P (Peer-to-Peer) transfers to high-volume P2M (Peer-to-Merchant) transactions. This trend analysis helps banks understand the decreasing reliance on physical cash and the increasing importance of digital touchpoints. Statement 2: The Internal Records System of a bank is sufficient on its own to perform this longitudinal analysis because all UPI transactions are routed through the bank's servers and recorded in the customer's account statement, eliminating the need for external marketing intelligence. Statement 3: Effective longitudinal analysis through an MKIS also requires monitoring the 'Decay Rate' of marketing information, which is the speed at which old data becomes irrelevant due to rapid changes in technology or consumer law. Based on these statements, identify the correct summary:

In the context of a bank's MKIS, consider the following situation: Statement 1: The bank uses its Marketing Intelligence System to observe that a new Fintech company has launched a zero-interest EMI product, which is gaining significant traction among the age group of 18 to 25. This is done through continuous review of financial news and competitor updates. Statement 2: To understand the specific impact, the bank initiates a Marketing Research project that involves surveying a sample of 1,000 customers from this age bracket. Statement 3: After gathering information, the bank uses its Marketing Decision Support System (MDSS) to run a simulation to see if launching a competing 'Buy Now Pay Later' (BNPL) product would be profitable. Which of the statements described above are correct?

Consider the following statements regarding the principles of Marketing Information System (MKIS) in banking: Statement 1: The Internal Records System provides the foundational data by documenting all customer-initiated transactions that are captured in real-time by the core banking software. It is considered a reliable source of information because it reflects actual historical behavior. Statement 2: The Marketing Intelligence System is essentially a specialized branch of MKIS focusing on systematic design and collection for specific problems on an ad-hoc basis, involving methods like focus groups and surveys. Statement 3: A longitudinal analysis of an MKIS requires maintaining a persistent and consistent data structure over many years so that the trends observed are not skewed by changes in definitions. Which of the following assessments is correct?
