AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Vitamins absent in the insect body system are D and K.Most insects derive their B vitamin requirements from the diet, microbial symbionts, or a combination of these complementary sources. Exceptionally, the genomes of a few insects bear genes in vitamin B5 (pantothenate) and B7 (biotin) synthesis, horizontally acquired from bacteria.
But they lack vitamin D and K in their bodies.
