This question is about naming India's 2019 anti-satellite missile test. Mission Agni, Mission Raftar and Mission Sahas can all be set aside together, since Agni actually refers to India's long range missile family and the other two names are not linked to any real defence programme of this kind.
The test that shot down a live satellite in low earth orbit was carried out by the DRDO under Mission Shakti in March 2019, making India only the fourth country after the US, Russia and China to demonstrate this capability.
So the correct answer is Mission Shakti.
The safest way to answer this is to separate the one option that is a genuinely different, unrelated defence programme from the two options that are not real programme names at all.
With Agni set aside as a real but different missile system, and Raftar and Sahas set aside as names without any matching programme, the anti-satellite test itself is tied only to one codename.
So the correct answer is Mission Shakti.
