To solve this problem, we need to identify the organization responsible for assessing the safety of introducing genetically modified organisms (GMOs) for public use in India. Let's analyze each option:$\newline \bullet$Option 1: Research Committee on Genetic Manipulation (RCGM)$\newline$ - RCGM is involved in monitoring research activities involving GMOs, but it is not the primary body for assessing safety for public use.$\newline \bullet$Option 2: Council for Scientific and Industrial Research (CSIR)$\newline$ - CSIR is a premier national R&D organization, but it does not specifically handle GMO safety assessments.$\newline \bullet$Option 3: Indian Council of Medical Research (ICMR)$\newline$ - ICMR focuses on biomedical research and does not primarily deal with GMO safety assessments.$\newline \bullet$Option 4: Genetic Engineering Appraisal Committee (GEAC)$\newline$ - GEAC is the apex body in India responsible for the approval of activities involving large-scale use of hazardous microorganisms and recombinants in research and industrial production. It is specifically tasked with assessing the safety of GMOs for public use.$\newline$Therefore, the correct option is Option 4: Genetic Engineering Appraisal Committee (GEAC).
