A
rocks
B
novae
C
energy (sunlight)
D
water
Explanation: 

Detailed explanation-1: -The most important parameter for Earth-like life is the presence of liquid water, which directly depends on pressure and temperature. Temperature is key both because of its influence on liquid water and because it can be directly estimated from orbital and climate models of exoplanetary systems.

Detailed explanation-2: -Liquid water is an essential requirement for life on Earth because it functions as a solvent. It is capable of dissolving substances and enabling key chemical reactions in animal, plant and microbial cells. Its chemical and physical properties allow it to dissolve more substances than most other liquids.

Detailed explanation-3: -Life as we know it requires biogenic elements, a source of energy, liquid water, and a suitable, reasonably stable environment for evolution to take place.

Detailed explanation-4: -All living things, from tiny cyanobacteria to giant blue whales, need water to survive. Without water, life as we know it would not exist. And life exists wherever there is water. All organisms, like animals and plants, use water: salty or fresh, hot or cold, plenty of water or almost no water at all.

Detailed explanation-5: -Water is vital for life. Clean freshwater is necessary for drinking and sanitation, providing for our crops, livestock and industry, and creating and sustaining the ecosystems on which all life depends.
