gnga-bhageerathee-hugalee jalamarga is the answer supported by the established record relevant to this First in India question. The correct answer is gnga-bhageerathee-hugalee jalamarga. The reference list identifies gnga-bhageerathee-hugalee jalamarga with the distinction “India’s first national waterway” and records the associated detail as prayagaraja se haldiya. Option-wise review: gnga-bhageerathee-hugalee jalamarga is correct for the exact category stated. naee dillee–havada is incorrect because it belongs to another achievement or field. pnbana pula is a valid name in Indian general knowledge, but it does not hold this precise record. munbaee se thane is also incorrect because its post, year, event, institution, or milestone association is different. Read “Indian,” “woman,” “independent India,” “individual,” “full-time,” “indigenous,” and the specified institution or event carefully. Therefore the answer field and correct index should point to option B, gnga-bhageerathee-hugalee jalamarga. The expression ‘first in India’ must be read precisely: the field, office, achievement, date and qualifying condition in the question all matter. The alternatives naee dillee–havada, pnbana pula, munbaee se thane belong to different achievements, periods or institutional roles.
