Task: Answer the multiple-choice question.
Query: Which drug has a 21.866\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccc(/C=[N+](\[O-])C2N(c3ccccc3)C(=S)SC2(C)C)cc1OC
b: COc1ccccc1CNC(=O)c1c(O)c2cc(OC)c(OC)cc2[nH]c1=O
c: CCCCNC(=O)CSc1nnc(-c2cccc(S(=O)(=O)N3CCOCC3)c2)o1
d: CCN1CCN(C(=O)/C=C/c2cccc(Cl)c2)CC1
e: CCOC(=O)C1CCN(S(=O)(=O)c2ccc(C)cc2)CC1
Answer: e. CCOC(=O)C1CCN(S(=O)(=O)c2ccc(C)cc2)CC1
