Answer 1

Option d is the correct answer as Europa that is the Jupiter’s second moon . The Europa initially might look like that it is very far away from the Sun to become a perfect candidate . The Europa Specifically has two special things due to which we have to suspect Europa that is : a ton of water which all togather will be greater than what we have on our earth and also it has some internal heating as well which is due to the specific tidal forces of the Jupiter which also increase the susceptibility that it can have life . Beneath a layer of ice the , Europa has a large ocean of liquid water in Europa , and all these will make an environment which is very similar to the specific kind of life-giving hydrothermal vents that we have on our Earth’s ocean floor. So the answer is Europa

Option a is wrong as venous has very high temperature that is 900 degrees Fahrenheit so not suitable for life when compared to europa

Option b is wrong as lo is not suitable for life when compared to europa

Pluto has very low temperature as it is very far away from the earth's surface and is almost 0 degree Celsius in temperature. So it is less favourable for life when compared to Europa . So option c is wrong answer

Mars option e is wrong as it is earlier had water as well as lakes but now it is less favourable for life when compared to europa
