Answer & solution

Answer: Option B

Two separate errors must both be fixed.

Error 1 — the idiom. The correct construction is regard as, never regard to be, regard for being or regard like.

Error 2 — the plural. The phrase one of the most significant… must be followed by a plural noun, because you are picking one item out of a group:

\text{one of the most significant scientific}discoveries

Testing each option against both rules:
