Answer: Option B

Solution

Answer: Option B
Solution:
A pesticide of lipophilic nature is DDT.
DDT is hydrophobic and lipophilic requiring an organic solvent (e.g., oil or fat) as a vehicle. Gastrointestinal absorption is slow with symptoms taking several hours to develop.
DDT is metabolized slowly by liver microsomal enzymes initially dehydrochlorinating DDT to DDE and reducing it to DDD.
