M/s. Sterling & Co LLP, Chartered Accountants are the statutory auditors of Green-Horizon Infrastructure Ltd. (GHIL), a listed entity. The management has requested the firm to draft and finalize their comprehensive Business Responsibility & Sustainability Report (BRSR) for the current fiscal year. CA Prem, the engagement partner, reviewed the section concerning the Company's influence on public and regulatory policy. The Company is a prominent "Platinum Member" of the National Infrastructure Council (NIC) and the Renewable Energy Federation (REF), paying substantial annual fees to these industry chambers. Additionally, the Company's CEO served as a key member of a Ministry-led task force that drafted the "National Green Hydrogen Policy 2024", providing extensive technical inputs on subsidies and regulatory easing. The Company also submitted a formal white paper to the Ministry of Power suggesting specific amendments to the Electricity Act regarding grid access. During the year, it had also submitted to one of the industry chambers certain key inputs on leveraging India's power infrastructure for creating renewable energy solutions as its task force member on the subject. The Managing Director argues that since the auditors are already the designated "Assurance Provider of BRSR Core" as per SEBI requirements, having them also prepare the underlying study would ensure maximum data consistency. He further contends that the firm can legally provide both preparation and assurance services for the same BRSR framework to an audit client. GHIL is currently undergoing an 80 crore expansion, called the 'Green Data Park'. The budget is allocated as 45 crore for cooling systems, 30 crore for civil construction (steel and cement), and 5 crore for licensing. An internal whistleblower alleged that the civil contractor, in collusion with the Project Manager, submitted invoices for 'Grade-A Steel' while installing 'Grade-B' material, pocketing the price difference. The Board is now debating the technical distinction between the two, asking CA Prem to perform 'extended audit procedures' on these construction invoices versus appointing a separate firm for a 'Forensic Accounting' engagement. Based on the above facts, answer the following Q. Nos. 10 to 12 by choosing the most appropriate option:
