A. was an underground remnant of Earth's earliest days, sporadically erupting B. had been an underground remnant of Earth's earliest days and sporadically erupted C. was an underground remnant of Earth's earliest days, which sporadically erupted D. would be an underground remnant of Earth's earliest days that sporadically erupted E. was an underground remnant of Earth's earliest days, having sporadically erupted

A. was an underground remnant of Earth's earliest days, sporadically erupting modifier problem sporadically erupting modifies Earth`s earliest days. B. had been an underground remnant of Earth's earliest days and sporadically erupted C. was an underground remnant of Earth's earliest days, which sporadically erupted same problem as AD. would be an underground remnant of Earth's earliest days that sporadically erupted not sure with D but i guess D also have modifier problemE. was an underground remnant of Earth's earliest days, having sporadically erupted modifier problem
I think its B

The OA is A
B suffers from parallelism problems, as it uses the verbs "had been" and "erupted"
A does not have a modifier problem. "Sporadically erupting" is clearly modifying molten rock.

Eliminated b,d,e. Between A and C. Explanation from MGMAT: The "ing" ending of erupting essentially allows this modifier to modify an entire clause instead of just the immediately preceding noun (which is the case, for example, in answer choice C - the "which" makes it a noun modifier and it would have to modify "days"). Which, who, where - all of those indicate noun modifiers (and noun modifiers, by definition, have to touch the noun they modify). therefore A

My thoughts.. Geologists once thought that the molten rock known as lava was an underground remnant of Earth's earliest days, sporadically erupting through volcanoes, but they now know that it is continuously created by the heat of the radioactivity deep inside the planet. A. was an underground remnant of Earth's earliest days, sporadically erupting - perfect & parallelB. had been an underground remnant of Earth's earliest days and sporadically erupted - had been is unnecessary, you need simple past tense. C. was an underground remnant of Earth's earliest days, which sporadically erupted - "which" incorrectly modifies "days" but we are attempting to modify molten rockD. would be an underground remnant of Earth's earliest days that sporadically erupted - "would be" is incorrect here. Wrong tense. They actually BELIEVED it was a molten rock, not that it "would be". Grammar & understanding the passage helps eliminate this. E. was an underground remnant of Earth's earliest days, having sporadically erupted - "having" is unnecessary. It also changes the meaning slightly.
