The correct answer is Option B (जळवा).

Key Points:
• This question tests the pluralization rules for feminine nouns ending in 'u' (ऊकारान्त स्त्रीलिंगी नाम).
• Rule: Feminine nouns ending in the 'u' (ऊ) vowel usually change their ending to 'va' (वा) in the plural form.

• Therefore, the correct plural form is 'Jalva'.
• Key Takeaway: Feminine nouns ending in 'u' form their plural by changing to 'va' (e.g., Jalu -> Jalva).
