Consider the following statements : 1. Genetic changes can be introduced in the cells that produce eggs or sperms of a prospective parent. 2. A person's genome can be edited before birth at the early embryonic stage. 3. Human induced pluripotent stem cells can be injected into the embryo of a pig. Which of the statements given above is/are correct ?

Option (D) is correct because all three statements describe technically feasible biotechnological processes: germline editing (Statement 1), embryonic genome editing (Statement 2), and the creation of inter-species chimeras using human iPSCs (Statement 3). Option (B) is the most tempting wrong choice as candidates often confuse the global ethical and legal restrictions on germline editing with its actual scientific possibility. The core concept tested is the technical scope and application of advanced genetic engineering tools (like CRISPR-Cas9) and stem cell research.
