With reference to the funds under Members of Parliament Local Area Development Scheme (MPLADS), which of the following statements are correct? 1. MPLADS funds must be used to create durable assets like physical infrastructure for health, education, etc. 2. A specified portion of each MP's fund must benefit SC/ST populations. 3. MPLADS funds are sanctioned on yearly basis and the unused funds cannot be carried forward to the next year. 4. The district authority must inspect at least 10% of all works under implementation every year. Select the correct answer using the code given below:

Option (d) is correct because MPLADS funds must be used for durable assets like health and education infrastructure (Statement 1), require mandatory earmarking for SC (15%) and ST (7.5%) populations (Statement 2), and necessitate a 10% annual inspection of works by the District Authority (Statement 4). Statement 3 is incorrect because MPLADS funds are non-lapsable, meaning unspent balances are carried forward to the next year, which makes options (b) and (c) wrong. The core concept tested is the operational guidelines and financial nature of the MPLADS scheme, specifically its focus on community asset creation and administrative accountability.
