regulations is that laws are:

B. Passed by the California Legislature and regulations are adopted by DPR
C. Created by counties while regulations are federal
D. Supplements to federal regulations
Correct Answer: B
Rationale: California pesticide laws are statutes passed by the state
legislature establishing the legal framework. The Department of Pesticide
Regulation (DPR) then adopts detailed regulations to carry out and
implement these laws. Both are mandatory, and county-level enforcement
supplements but does not replace state law .
