Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 18.889% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CCO[C@@H]1OC(C(N)=O)=C[C@H](C(C)(C)C)[C@H]1CCCO
b. COc1cc(/C=N/NC(=O)c2cccc([N+](=O)[O-])c2)ccc1OC(=O)c1ccco1
c. O=C(COc1ccc(Br)cc1)N1CCNC1=O
d. COc1ccc(CNc2nc(SC)n[nH]2)cc1OC
e. Cc1ccc(N(C(=O)c2snc(C(N)=O)c2N)C(C(=O)NC2CCCC2)c2ccncc2)cc1
Answer: a. CCO[C@@H]1OC(C(N)=O)=C[C@H](C(C)(C)C)[C@H]1CCCO
