I think the correct answer would be option A. This passage uses a combination of comparison and contrast and cause and effect. The use of "both", "however" and "on the other hand" are indications that the passage is using compare and contrast principle. Also, it states several sentences that cause why these particular substance are formed for a longer time and what are the processes involved like the phrase "because it took that much time for overlying sediments to produce the unimaginable heat and pressure". Along with this, the effect is stated. So, most likely, the passage above is also using the cause and effect organizing principle.
