Solution

To find the relationship between Bravo and Ziva, we must construct the family tree from the clues.

• "Bravo and Priya are siblings."
• "Kajal is Priya's mother-in-law." This means Priya is married to Kajal's son.
  
• "Sam is the brother-in-law of Bravo." Since Bravo is Priya's brother, the simplest conclusion is that Sam is Priya's husband. This makes Sam the son of Kajal.
  
• "Ziva is a married woman." The only remaining core male character whose spouse isn't identified is Bravo. To connect all eight members, it is logical that Ziva is married to Bravo.

Conclusion:

If Ziva is married to Bravo, then Bravo is Ziva's Husband.
