210. Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.
A. extending
B. extends
C. extended
D. it extended
E. is extending
Choice A, the best answer, preserves grammatical parallelism while allowing for logical expression of temporal relationships; A employs the parallel participial phrases spawned... and extending ... to modify filigree. Other choices present different grammatical constructions that are not participial modifiers and thus not parallel to spawned: extends in B is a present-tense verb; it extended in D begins a new clause; and is extending in E ungrammatically introduces a new predicate. In C, extended is nonparallel if it is assumed to be a past tense verb form; if it is assumed to be a past participle, it illogically states, as does D, that the filigree extended only in the past.
我还是不明白为什么选A，知道所缺的词应和spawned平行，我觉得选B更好点。搞不明白为什么要用现在进行时态？是因为这个家伙还一直在长着么？
If you want "extend," I can do it for you:

Since the above sentence has two "that" clauses, it is not that good, so changing it into two 分词 从句 is better. That's the reason why we have A as the correct choice.
