B. Both genetic and environmental factors.
Explanation: Genetic makeup sets each tilapia's growth potential (growth rate, feed conversion, disease resistance), while environmental conditions determine how much of that potential is realized. Key environmental factors include temperature, dissolved oxygen, water quality (pH, ammonia), feed type/quantity and feeding regime, stocking density, salinity, light, and disease/parasite pressure. Genotype-by-environment interactions mean different strains may respond differently to the same conditions.
