Why is a margarine solid

However, hydrogenation (the process for making margarine) involves breaking double bonds and adding hydrogen atoms so that the unsaturated fat becomes “more saturated” than before by breaking double bonds and most likely making it solid instead of liquid at room temperature.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
