The development of the disease was INSIDIOUS.

  • A. Momentous
  • B. Sudden
  • C. Innocuous
  • D. Gradual
Correct Answer: D

Rationale: The term 'insidious' describes something that proceeds in a gradual, subtle way with harmful effects. In this context, it implies that the disease developed slowly and subtly rather than suddenly or in a momentous manner. 'Momentous' means significant or important, 'sudden' means happening quickly or unexpectedly, and 'innocuous' means harmless. Therefore, the correct answer is 'D: Gradual.'
