An herbicide is a weed killer. It is very harmful to plants, so the correct answer would be D. The herbicide would kill the native plants.
I believe A is the most correct (i assume it's about antibiotics - they actually DO harm our immune system in some way).
B is partially correct because, the colds indeed should be treated by anti-viral medication (because the virus is a cause of typical cold) but using antibiotics during recovery is needed only when an additional bacterial infection occurs as a complication after the viral infection. and it doesn't happen very often.
C - what works? antibiotics doesn't work for viral infections (colds). anti-viral medication do.
D i won't discuss.

A peritonsillar abscess is a bacterial infection that is caused by untreated tonsillitis and strep throat. Complications can be infected lungs causing airway obstruction. Antibiotics are the treatment for this condition or the pus may be drain such as that of a Percutaneous Needle Aspiration thus the nurse should be able to impart to the client to follow the medication prescribed especially antibiotics like if it is good for 7 days to finish it and if in case complications would arise, the patient should consult medical help.
