[A] UAE

[B] USA

[C] China

[D] Israel

Answer: B
Notes:

Explanation:

  1. NASA’s InSight Mars lander detected the largest quake that was ever observed on another planet. The rover landed on Mars in November 2018 and has heard 1,313 quakes so far, of which the largest “Marsquake” was detected in August 2021.
  2. On Earth the quakes are caused by shifts in tectonic plates, but Mars does not have tectonic plates and its crust is a giant plate. As per the NASA, the ‘marsquakes’ are caused due to stresses that cause rock fracture in its crust.
