BAntibiotics are only effective against fungi

DThe cold virus is too small for antibiotics to reach
Answer & Solution
Correct answer: C. Antibiotics work against bacteria, not viruses, and the common cold is caused by viruses
Antibiotics interfere with bacterial cell processes (e.g. cell-wall synthesis or protein synthesis). Viruses lack those targets and reproduce inside our own cells, so antibiotics cannot harm them. Cold and flu, being viral, are unaffected by antibiotics.
