Final answer:
The correct answer is topical.
Step-by-step explanation:
Parenteral administration refers to the delivery of medication through routes other than the digestive tract, such as intravenous or intramuscular injections. The question asks which form is NOT supplied for parenteral administration. The correct answer is topical, as topical medications are applied directly to the skin or mucous membranes and do not involve injection. The other options - oral, intravenous, and parenteral - are all valid forms of medication delivery for parenteral administration.
