Plz asap a
which major processes were needed for the origin of life on
a. abundance of oxygen in the o-zone layer
b. active volcanoes in very cold temperatures
c. low levels of ultraviolet radiation and specific mixture of gases
d. organic molecules produced from spontaneous synthesis or from meterorites

See explanation

Explanation:

I feel as though this is a multiple choice question, in which you are allowed to pick multiple answers with the given choices.

If so, then I would like to point out the following:

D) The formation of these Organic Molecules were first and foremost THE most crucial part in the becoming of life. Without their formation, life would likely cease to exist entirely in this solar system. These "molecules" are more accurately dubbed ABIOTIC molecules, and they included essentials to life such as amino acids and nucleotides, which led to abiotic synthesis. For this to begin, all that's needed is time, something to build from, Absolute minimal (or better yet, 0) oxygen, and ofc what our galaxy was birthed from, ENERGY. These abiotic molecules and the process of abiotic synthesis ofc directly led to the formation of organic molecules that are now what comprise LIFE itself.

A) Abundance of Oxygen in the O-zone layer.

A vast majority of life that has existed or still exists today required no other source to assist with their respitoration systems other than oxygen. Without it, life certainly wouldn't be around today, at least, not life as we know it.

However, if this is only a question that allows one answer, your answer is D. If multiple answers are allowed, then D and A.

Eliminate B and C.
