A) 12
B) 18
C) 24
D) 30
Accumulated Degree Hours
A measure used in forensic entomology to estimate the age of a maggot in a corpse, based on the accumulation of hourly temperatures above a threshold.
Larva
The juvenile form of many animals before undergoing metamorphosis, often differing significantly in form and habit from the adult stage.
Develop
To grow or cause to grow and become more mature, advanced, or elaborate.
- Familiarize yourself with the notion of accumulated degree hours (ADH) and the way temperature modifies insect development.

Final Answer :
B
Explanation :
Accumulated Degree Hours (ADH) is calculated by multiplying the number of hours by the difference between the temperature and a base temperature (usually the minimum temperature required for development). Assuming a base temperature of 0°C for simplicity, 486 ADH at 27°C would require 486 / 27 = 18 hours.
