Which of the following reagents can be used to convert cyclopentanol to cyclopentane?

A) TsCl, pyridine followed by LiAlH₄
B) Na₂Cr₂O₇, H₂SO₄
C) NaBH₄ followed by H₃O⁺
D) H₂SO₄, heat followed by H₂, Pt
E) both A and D

Options A and D describe reagents that can facilitate the conversion of cyclopentanol to cyclopentane. Option A involves the formation of a tosylate followed by reduction with lithium aluminum hydride (LiAlH4), a strong reducing agent capable of removing the oxygen atom. Option D involves the use of hydrogen sulfide and heat, followed by catalytic hydrogenation over platinum, which can also effectively remove the oxygen atom, converting an alcohol to an alkane.
