  3. Both 1 and 2
  4. Neither 1 nor 2

Answer

Both 1 and 2

1. Targeted drug delivery is made possible by nanotechnology. Nanoparticles can be engineered to carry drugs to specific tissues/cells, improving targeted delivery and reducing side effects. Verdict: Correct.

2. Nanotechnology can largely contribute to gene therapy. Nanocarriers such as liposomes and polymer nanoparticles help deliver genes/siRNA safely into target cells, so nanotechnology is an important tool in gene therapy. Verdict: Correct.

Since both 1 and 2 are correct, the answer is (c).
