Q. With reference to Hycean worlds, consider the following statements.
1. Hycean planets are up to 2.5 times bigger than Earth, with oceans and hydrogen-rich atmospheres.
2. These planets might support microbial underwater life.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Both the statements are correct. 

A recent study published in The Astrophysical Journal identifies a new class of exoplanets – Hycean worlds – that could support life different from that on Earth. 

These planets are about 2.5 times the size of Earth, have temperatures about 200 degrees Celsius and planet-wide oceans. These could support microbial underwater life.
