Hint:

Naringenin is the characteristic "Flavanone" of citrus fruits.

Answer 1

The Correct Option is B

Step 1: Concept
Flavonoids are a large class of plant secondary metabolites categorized by their specific chemical skeleton.

Step 2: Meaning
Flavanones are characterized by the absence of a double bond between C2 and C3 in the flavonoid nucleus.

Step 3: Analysis
Naringenin, commonly found in citrus fruits like grapefruit, lacks the C2-C3 double bond and the C3-hydroxyl group, which classifies it chemically as a flavanone.

Step 4: Conclusion
Thus, naringenin is accurately identified as a flavanone.

Final Answer: (B)
