Answer:
Option B, not phosphorylated; inhibited
Explanation:
Glucose 6 acts as a catobolite repressant . A catobolite repressant which is usually a carbon compound inhibits the operon transcription. In the presence of glucose -6, unphosphorylated enzyme IIAGlc inhibits the transportation system and hence prevents the utilization of lactose. Glucose‐6‐phosphate and other non‐PTS carbon causes inducer exclusion thereby leading to dephosphorylation of enzyme IIAGl without getting transported.
Hence, option B is correct

By age group, in 2019, the number of new HIV diagnoses was highest among people aged 25 to 29. From 2015 through 2019, HIV diagnoses increased among persons aged 13-24 years, 35-44 years, and 45-54 years.
The best answer is C.
Chloroplasts are not found in all eukaryotic cells but only in plant cells. Animal cells are eukaryotic in nature but animals do not have chloroplasts in their cells because they do not engage in photosynthesis.
Photosynthesis is the process by which plants make their own food. Chloroplasts contain chlorophyll which is essential in t trapping sunlight from which supplies the energy for photosynthesis.
Animals do not make their own food like plants but eat ready made food so their cells lack mechanisms for food manufacture.
