Option 1 -> EOS-07 is part of India's Earth Observation Satellite series, specifically designed to monitor Earth's surface, resources, and environment.
Option 2 -> Aditya-L1 is India's solar mission positioned at the L1 Lagrange point to study the Sun, not Earth.
Option 3 -> GAGAN (GPS Aided Geo Augmented Navigation) is a satellite-based navigation augmentation system to improve GPS accuracy, not for Earth observation.
Option 4 -> INS-1C is part of the Indian Nanosatellite series primarily for technology demonstration and experimental payloads.
Hence, Option 1: EOS-07 -> The EOS (Earth Observation Satellite) series is ISRO's dedicated program for remote sensing and Earth observation applications, including land, water, and atmospheric monitoring -> correct
