Option 1 states that viruses are "non-living" entities, but they can interact with antibodies. This statement is incorrect because viruses are actually considered to be "obligate intracellular parasites" which means they are living organisms that rely on host cells for their replication. However, they cannot interact with antibodies in the same way bacteria or other infectious agents can.

Option 2 states that taking antibiotics cures viral infections. This statement is incorrect because antibiotics are specifically designed to target bacteria, not viruses. They work by inhibiting or killing bacteria by targeting specific metabolic pathways or cellular structures. They do not have any effect on viruses.

Option 3 is the correct statement. It states that viruses do not possess metabolic pathways on which antibiotics can function, whereas bacteria have such pathways. This means that antibiotics are ineffective against viruses because viruses do not have the same cellular structures or processes that antibiotics can target. Antibiotics are only effective against bacteria, which have specific metabolic pathways that can be disrupted by antibiotics.

Option 4 states that viruses are resistant to antibiotics. This statement is incorrect because resistance to antibiotics is a characteristic of bacteria, not viruses. Viruses do not have the same types of cellular structures or mechanisms that bacteria have, so the concept of antibiotic resistance does not apply to them
