Viruses are metabolically inert outside a host cell and lack the enzyme systems needed to generate ATP or other energy molecules, so statement 1 is correct. They cannot be grown on artificial nutrient media but require living cells, making statement 2 wrong, and they may spread through mechanical means (air, contact, water) as well as biological vectors, so statement 3 is also wrong; therefore only statement 1 is correct.
