WebSep 16, 2024 · 1 Answer. Lithium Aluminium Hydride reduces epoxides1, hence (A) would not give the required product. LAH also reduces ethers to primary alcohols, which is an easier way of eliminating the option (A). B H X 3 in THF can reduce the acid, as explained in this question, hence the requisite product would not be obtained.
