Show answer and explanation

Correct answer: MTA

Explanation

The final official key awards marks to all, so no option is enforced. CARTOSAT is the intended high-resolution Indian mapping family, but resolution depends on the particular satellite/sensor and product. LANDSAT and MODIS are not Indian satellite families. Retain the withdrawn/MTA grading rather than silently assigning B.
