[求助]托福阅读-词汇题 需要关注选项代入后的语法问题吗?

RT. 只是要和原来的词汇在句中含义相同即可，还是要保证选项代入句子后语法仍然通畅?

e.g.[TPO4中的一篇阅读:Petroleum Resources]
Petroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment. Microscopic organisms settle to the seafloor and 【accumulate】 in marine mud. The organic matter may partially decompose, using up the dissolved oxygen in the sediment. As soon as the oxygen is gone, decay stops and the remaining organic matter is preserved.

The word 【accumulate】is closest in meaning to:
A:grow up
B:build up
C:spread out
D:break apart

答案选了B选项build up, build up本身代入原文似乎在语法上有问题。而A选项代入感觉很match啊...

向各位大牛求助！

既然grow up你觉得没有语法问题  build up有什么问题呢？   注意grow up的意思是to grow toward or arrive at full stature or physical or mental maturity <growing up intellectually, socially, and physically 而build up的意思是to develop gradually by increments  
accumulate的意思是to gather or pile up especially little by little    AB谁对谁错一目了然啊  我倒是觉得即使有的题语法可能有问题 也要优先closest in meaning
