1.It is the world’s first satellite to combine optical imaging and Synthetic Aperture Radar (SAR) capabilities on a single platform.
2.The satellite can capture high-resolution images both during day and night and even through cloud cover.
3.It is a purely radar-based satellite and does not use any optical sensors for imaging.
Which of the statements given above is/are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: A
Notes:

Explanation: 1 and 2 only

Statement 1 is correct: OptoSAR integrates optical + SAR sensors, a first-of-its-kind design.

Statement 2 is correct: SAR allows all-weather, day-night imaging, while optical adds high-detail imagery.

Statement 3 is incorrect: It is not purely radar-based; its key innovation is combining both systems.
