munbaee is the answer supported by the established record relevant to this First in India question. The correct answer is munbaee. The reference list identifies munbaee with the distinction “India’s first sarvajanika basa seva” and records the associated detail as 1926. Option-wise review: munbaee is correct for the exact category stated. pnbana rela pula is incorrect because it belongs to another achievement or field. munbaee se thane is a valid name in Indian general knowledge, but it does not hold this precise record. naee dillee–havada 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 D, munbaee. The expression ‘first in India’ must be read precisely: the field, office, achievement, date and qualifying condition in the question all matter. The alternatives pnbana rela pula, munbaee se thane, naee dillee–havada belong to different achievements, periods or institutional roles. A reliable revision method is to record the pair ‘Which option correctly identifies India’s first sarvajanika basa seva? — munbaee’ together with its field and historical context.
