Step 1: Understanding the Concept:
Traditional papaya (*Carica papaya*) fruits contain volatile sulfur compounds and carpaine compounds that produce a distinct, pungent odor.
This odor can be unappealing to some consumers, so breeding programs focus on developing hybrids with improved organoleptic qualities.
Step 2: Detailed Explanation:
The Indian Institute of Horticultural Research (IIHR) in Bengaluru developed two prominent gynodioecious papaya hybrids with excellent fruit quality:
1. Arka Surya (B): A hybrid developed from a cross between *Solo* and *Sunrise Solo*. It produces sweet, firm, deep-pink pulp that is completely free from the typical off-putting papaya odor.
2. Arka Prabhath (A): An advanced generation hybrid developed from a complex cross involving *Surya*, *Solo*, and *Coorg Honey Dew*. It produces sweet, firm, deep-orange pulp that is also completely free from the typical papaya odor.
The other varieties mentioned (*CO 5* and *Solo*) are traditional selections that retain the typical papaya aroma.
Therefore, only Arka Prabhath and Arka Surya are free from the typical papaya odor.
Step 3: Final Answer:
The correct option is (A) and (B) only, corresponding to option (B).
