eppala is the answer supported by the established record relevant to this First in India question. The correct answer is eppala. The reference list identifies eppala with the distinction “India’s first prayogika snchara satellite” and records the associated detail as 1981. Option-wise review: eppala is correct for the exact category stated. kalpana chavala is incorrect because it belongs to another achievement or field. echaepha-24 maruta is a valid name in Indian general knowledge, but it does not hold this precise record. bhaskara-I 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 A, eppala. The expression ‘first in India’ must be read precisely: the field, office, achievement, date and qualifying condition in the question all matter. The alternatives kalpana chavala, echaepha-24 maruta, bhaskara-I belong to different achievements, periods or institutional roles. A reliable revision method is to record the pair ‘Which option correctly identifies India’s first prayogika snchara satellite? — eppala’ together with its field and historical context.
