Correct option is A
Given:
Tablet, Ointment, and Injection are forms of medication — they refer to the physical means through which medicine is administered.
Treatment, on the other hand, is a broader term that refers to the overall process of curing or managing a disease, which may involve one or more of the other options.
Let's define all the options:
(a) Treatment – Overall process of curing a disease (broad term)
(b) Tablet – Solid form of medicine taken orally
(c) Ointment – Semi-solid medicine applied on the skin
(d) Injection – Medicine given via syringe into the body
All options except Treatment are specific forms of medicine. Hence, Treatment is the odd one out.
Thus, the correct option is (a) Treatment.
