HELP M Scientists previously thought that chemicals used as propellants in aerosol cans had noeffect on the environment. Then a pair of scientists hypothesized that these propellants could break down ozone in the atmosphere. How did scientists use logical reasoning to determine that the propellants might be harming the environment after all? a. The scientists discovered that the hole in the ozone layer over Antarctica was growing larger
.b. The scientists discovered that the levels of the propellants in the atmosphere were increasing.
c. The scientists created a computer model to trace the origins of the propellants in the atmosphere.
d. The scientists identified possible reactions between the propellants and chemicals known to be in the atmosphere.
