"A disease always has ______."
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Cause
The answer must hold for every disease, without exception. An option that is present in most cases but can be missing in even one case is not always true.
Option (1) Cure — some diseases have no cure even today.
Option (2) Medicine — not every disease has a medicine; some are only managed by diet or rest.
Option (3) Cause — every disease arises from some cause, such as germs, poor diet, injury or a fault in the genes, so this is always true.
Option (4) Germs — deficiency diseases such as scurvy and genetic diseases are not caused by germs.
