With reference to the use of nano-technology in health sector, which of the following statements is/are correct? 1. Targeted drug delivery is made possible by nanotechnology. 2. Nanotechnology can largely contribute to gene therapy. Select the correct answer using the code given below.

Both statements are correct because nanoparticles can be engineered to release drugs specifically at diseased sites (targeted delivery) and serve as efficient non-viral vectors to transport genetic material into cells for gene therapy. Option (a) is the most tempting wrong choice for candidates who recognize the well-known role of nanotechnology in drug delivery but underestimate its advanced applications in genetic engineering. The core concept being tested is the versatility of nanomaterials as precise delivery vehicles in biotechnology and medicine.
