the type of error that typically justifies remand. Id. at 1217; see Huffman, 194 F.3d at 1077-79 (defendant’s failure to file notice of removal within the thirty-day period necessitated remand upon plaintiffs motion); see also Cornwall v.

What is the most suitable continuation to the opinion? Your options are:
A. holding that a defendants failure to attach process to its notice of removal was not fatal and did not require remand
B. holding that failure to allege plaintiffs citizenship in notice of removal amounted to defect in removal procedure under former version of 28 usc  1447c
C. holding that the defendants motion to amend their notice of removal was proper due to plaintiffs waived objections to the sufficiency of the notice of removal by failing to seek remand within thirty days of removal
D. holding that any defect in removal procedure must be cured within the 30day removal period or it is fatal to the removal and defendants failure to attach exhibits to the notice of removal within that time required remand
E. holding that the defendants filing of a notice of removal before being served by plaintiffs did not render removal defective
